Bug 1113930 seems similar.

We're hitting a debug break point. We're trying to print the stack to show where we are but we're filling. This is the indirect problem of what we're doing. Note that I'm not saying that's it's not worth fixing. http://mxr.mozilla.org/mozilla-central/source/mozglue/misc/StackWalk.cpp#893 I moved the code recently but I don't know this code very well. Crash address is at 0x3 so most likely have a null value incremented by 0x3 or get a bogus value of 0x3. It would be best if someone can attach a debugger and dig down into this.

Ted, BenWa nominated you on IRC to chime in here. This is a permafail so we really need to keep it moving forward :)

Note that this is Linux32 PGO only. We had the same issue with Aurora41 in bug 1113930 on an FHR uplift. Dexter has some investigation in there as well.

So we're in FramePointerStackWalk, but it looks from the stack like ebp isn't the frame pointer. It looks like we're falling FramePointerStackWalk with a |bp| of 0x3. We could do the 0x3 test on it like we do on its dereferenced value, but the other two (more important) validity tests won't work there. Being able to fix this mess in MozStackWalk: https://hg.mozilla.org/releases/mozilla-aurora/file/a695ecb82d4d/mozglue/misc/StackWalk.cpp#l938 would probably help; not sure if that comment about __builtin_frame_address being broken on i386 is still true.

Looks like the real problem, as Ted points out, is that we might be getting a glib assertion: https://dxr.mozilla.org/mozilla-central/source/toolkit/xre/nsSigHandlers.cpp#140 We could call pthread to get the stack end which would be more robust then checking for a magic value of 0x3.

(In reply to Benoit Girard (:BenWa) from comment #14) > We could call pthread to get the stack end which would be more robust then > checking for a magic value of 0x3. We already have the stack end; we don't have the start (though we could probably get it), and we're only testing & 0x3 as a sanity-check for alignment.

So the disassembly gives this away: Aurora is not compiled with --enable-profiling, so it doesn't have a frame pointer (note that in the crashing instruction it's moving the value *into* %ebp). We're just passing whatever junk is in %ebp into this function and crashing at the first dereference. If we had a "stack start" we could change "while (bp)" into "while (bp > stack_start)". A simple bandaid fix might be "while (bp > 4096)" or something silly like that, but that'd still let us fail if we get a non-pointer value in %ebp. We could condition the use of FramePointerStackWalk on MOZ_PROFILING, since there's no direct way to check whether we have frame pointers enabled at compile time.

(In reply to Ted Mielczarek [:ted.mielczarek] from comment #17) > We could condition the use of FramePointerStackWalk on MOZ_PROFILING, since > there's no direct way to check whether we have frame pointers enabled at > compile time. Yea, honestly I have no idea how things ever worked without that check. Or we could refuse to run FramePointerStackWalk and just return an empty list. I actually assumed that was already the case. I think some of our Stackwalking code implementation does this already. I'd be fine with landing either IMO.

This should not be called if we're not using MOZ_PROFILING: http://mxr.mozilla.org/mozilla-central/source/xpcom/base/nsTraceRefcnt.cpp#872

Anyone know if doing a PGO build should involve using MOZ_PROFILING? I can't find in the build code why we would be requiring this. Here's some diagnostics: https://treeherder.mozilla.org/#/jobs?repo=try&revision=2d05df81c70c

So the diagnostics confirm that the build is getting MOZ_PROFILING. It's not clear to me from the dis-assembly if it is being build with frame pointers if someone can weight in? We might be mismatching MOZ_PROFILING and frame pointers flag in PGO builds. I could find from the build system why PGO aurora builds would get MOZ_PROFILING. Any idea glandium?

(In reply to Benoit Girard (:BenWa) from comment #29) > So the diagnostics confirm that the build is getting MOZ_PROFILING. Where? The build log on your try build doesn't show the echo you added, nor --enable-profiling in the configure flags used.

*And* the build log shows compiles are using -fomit-frame-pointer
