STR: 1) Set media.navigator.permission.disabled=true to work around Bug 973001 2) go to http://apprtc.appspot.com 3) Copy URL and paste it in second tab to establish call 4) crash, see callstack Thread 31 Compositor, Queue : (null) #3 0x0000000101e27fe9 in mozilla::layers::PImageBridgeParent::DeallocShmem(mozilla::ipc::Shmem&) at /Users/Jan/moz/mozilla-central/obj-x86_64-apple-darwin12.2.1-debug/ipc/ipdl/./PImageBridgeParent.cpp:838 auto PImageBridgeParent::DeallocShmem(Shmem& aMem) -> bool { bool ok = DestroySharedMemory(aMem); #ifdef DEBUG if ((!(ok))) { -> NS_RUNTIMEABORT("bad Shmem"); } #endif // DEBUG (aMem).forget(Shmem::IHadBetterBeIPDLCodeCallingThis_OtherwiseIAmADoodyhead()); return ok; }

Might be a dupe of bug 972623 - specifically the 2nd patch in https://bugzilla.mozilla.org/attachment.cgi?id=8376643&action=diff.

I tried with both patches as well as with a fresh pull and the problem still happens, so it doesn't look to be a dupe.

I experienced repeated tab crashes today (in an e10s window) with a loop call. Is this the same bug or should I report another?

Moving old M2 P1 bugs to M3.

Would you mind taking this over, Jan?

The original bug was not an intermittent, and it would crash all the time for me. I can no longer reproduce this so it appears to have fixed itself at some point. I suggest we open new bugs for new crashes.
