User Agent: Mozilla/5.0 (X11; OpenBSD amd64; rv:37.0) Gecko/20100101 Firefox/37.0
Build ID: 20150408192825

Steps to reproduce:

I'm trying to watch the latest BSDNow.tv episode in Firefox and it works
perfectly fine until
they go to discuss port reviews by the end of the episode.

I managed to reproduce the crash twice so far, always resulting in the
same segmentation
fault that looks like coming from gstreamer.

Running:
 amd64 snapshot from Apr 9 GENERIC.MP + a re0 patch from Brad Smith
 Gnome 3.16.0
 firefox-37.0.1 (installed)
 etc/login.conf :datasize-cur=1536M
 dmesg at the far end
 
Steps to reproduce:
 1. Start firefox
 2. Navigate to:
 http://www.bsdnow.tv/episodes/2015_04_08-pkg_remove_freebsd-update
 3. Press play - keep on 360p
 4. Skip to 1h 10m
 5. Wait for Chris to speak.
 6. There is a slight chance that the browser will crash when Allan
 talks before they both
     get to OpenBSD content.

Possible workarounds:
 - youtube-dl the epsisode & play in mplayer/vlc
 - watch the video in 720p (not able to reproduce crash when video is on
 720p)

Crash reproduced 4 times:
 1) 16:12 (783M core dump)
 2) 16:22 (572M core dump)
 3) 16:24 (270M core dump)
 4) 16:28 (263M core dump)

The reason for the core dumps getting smaller is me narrowing down the
issue.
First test runs had more tabs open, last two tests were done with no
other tabs
than the linked bsdnow.tv page.

Allan Jude on twitter (https://twitter.com/allanjude/status/587299374528512000) suggested it might be:
 - https://www.mozilla.org/en-US/security/advisories/mfsa2015-31/
though that tweet was most probably a joke but I don't know how to verify if that patch is included
in my Firefox build.

This issue was originally reported to the OpenBSD mailing lists:
 - http://marc.info/?l=openbsd-ports&m=142884995931428&w=2


Actual results:

$ firefox 
Segmentation fault (core dumped)

Expected results:

Being able to watch the video up to the end without the browser crashing.

That kind of joke is .. not funny. The actual MFSA was fixed in 37.0 so your build had it.

To add another data point, is it with gstreamer1-1.4.5 and more or less the same version for the gstreamer plugins ?

Correct. Here are my gstreamer & plugins plugins:
# pkg_info -Q gstreamer | grep -i installed
gstreamer1-1.4.5 (installed)
gstreamer1-plugins-base-1.4.5 (installed)
gstreamer1-plugins-good-1.4.5p1 (installed)
gstreamer1-plugins-libav-1.4.5 (installed)
gstreamer1-plugins-ugly-1.4.5 (installed)

It's also worth to add that I downloaded the whole episode with youtube-dl
and played it without any issues in Totem which also uses the gstreamer backend.

Havent been able to reproduce so far with 38.0b3, but youtube/video playback is barely usable on my desktop even at 360p.

I can provide a core dump from the last crash privately to you Landry.
Would that help?

gdb is unusable to debug anything "big" on OpenBSD.

One of my friends took a look at it back then:
 - https://www.marc.info/?l=openbsd-ports&m=142496891206563&w=1

Though that crashes don't have gstreamer on their path (they start from JS). The only
common crash point is workerlz4_maxCompressedSize and it was from Firefox 35.

Is 37.1 compiled with enabled assertions like 35.0.1 was?

The same configure options were used - dunno what you think about when you say 'assertions' here..

Sorry for being unclear.

In the i386 bug report I linked the common code paths were:

(this is the i386 OLD backtrace, possibly not related to this issue)
#0  0x0399f481 in kill () at <stdin>:2
#1  0x039dd876 in raise (s=11) at /usr/src/lib/libc/gen/raise.c:39
#2  0x0b6eae52 in workerlz4_maxCompressedSize () from
/usr/local/lib/firefox-35.0.1/libxul.so.53.0

compared to the new one
(this is the current backtrace, for this issue)
#0  0x000018db1edae9ba in kill () at <stdin>:2
2       <stdin>: No such file or directory.
        in <stdin>
(gdb) bt
#0  0x000018db1edae9ba in kill () at <stdin>:2
#1  0x000018db3abf43a4 in workerlz4_maxCompressedSize () from
/usr/local/lib/firefox-37.0.1/libxul.so.55.0

When you look at the definition of maxCompresseSize:
  /*
   * Provides the maximum size that LZ4 may output in a "worst case"
   * scenario (input data not compressible) primarily useful for memory
   * allocation of output buffer.
   * note : this function is limited by "int" range (2^31-1)
   *
   * @param aInputSize is the input size. Max supported value is ~1.9GB
   * @return maximum output size in a "worst case" scenario
   */
  static inline size_t maxCompressedSize(size_t aInputSize)
  {
    size_t max = (aInputSize + (aInputSize / 255) + 16);
    MOZ_ASSERT(max > aInputSize);
    return max;
  }

It seems that the old bug 'died' on the assertion:
#1  0x039dd876 in raise (s=11) at /usr/src/lib/libc/gen/raise.c:39
#2  0x0b6eae52 in workerlz4_maxCompressedSize () from

The new code shares the entry point of workerlz4_maxCompressedSize
thoug:
#1  0x039dd876 in raise (s=11) at /usr/src/lib/libc/gen/raise.c:39
is not present on the amd64 box.

That's the reason I was thinking those issues might be related or
being trapped by the same: MOZ_ASSERT(max > aInputSize);

Though on my part it's just a guess, hope it doesn't introduce misinformation.

Experienced the crash again but this time while watching Youtube.
Came from a different codec but resulted also in a crash in workerlz4_maxCompressedSize.

I can't pin point the actual video as it was a random vid from Youtube music.

Can i chime in, guys?

I'm coming from the FreeBSD world to share a few traces and thoughts about this one.

First, someone already reported that bug at: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=198902

The code block that MOZ_ASSERT is guarding is one line long and the only possible reason for ASSERT to fire up is giant aInputSize that make size_t overflow:

#include <stddef.h>
#include <stdio.h>

int main(void) {
  size_t x = 18446744073709551615UL;
  size_t y = (x + (x / 256) + 16);
  printf("%zu\n%zu\n", x, y);
  return(0);
}

This code compiles perfectly for me resulting in:

18446744073709551615
72057594037927950

So here we have an overflow.

I think MOZ_ASSERT can be traded for NS_WARNING here:

  static inline size_t maxCompressedSize(size_t aInputSize)
  {
    size_t max = (aInputSize + (aInputSize / 255) + 16);
    if (max > aInputSize) {
      NS_WARNING(nsPrintfCString("maxCompressedSize overflowed: %zu", aInputSize).get());
      return(SIZE_MAX);
    }
    //MOZ_ASSERT(max > aInputSize);
    return max;
  }

I think the bug is not actually in the compression code, it's rather a mandelbug that makes process fail here when some other part of code requests too big memory chunk.
