There's a new intermittent orange which shows up as: PROCESS-CRASH | /tests/toolkit/devtools/apps/tests/test_webapps_actor.html | application crashed [@ mozilla::layers::ISurfaceAllocator::~ISurfaceAllocator] though I think it's really a shutdown crash that just happens to be attributed to the last test. 20:03:54 INFO - CPU: arm 20:03:54 INFO - 0 CPUs 20:03:54 INFO - Crash reason: SIGSEGV 20:03:54 INFO - Crash address: 0x0 20:03:54 INFO - Thread 0 (crashed) 20:03:54 INFO - 0 libxul.so!mozilla::layers::ISurfaceAllocator::~ISurfaceAllocator [ISurfaceAllocator.cpp:184bbe9eacf4 : 53 + 0x4] 20:03:54 INFO - r4 = 0x446856a0 r5 = 0x446856d8 r6 = 0x446856a0 r7 = 0x00000000 20:03:54 INFO - r8 = 0x00000001 r9 = 0x00000000 r10 = 0x44160040 fp = 0x00000001 20:03:54 INFO - sp = 0xbead9730 lr = 0x40e2017d pc = 0x40e20180 20:03:54 INFO - Found by: given as instruction pointer in context 20:03:54 INFO - 1 libxul.so!mozilla::layers::CompositableForwarder::~CompositableForwarder [CompositableForwarder.h : 45 + 0x5] 20:03:54 INFO - r4 = 0x446856a0 r5 = 0x446856d8 r6 = 0x446856a0 r7 = 0x00000000 20:03:54 INFO - r8 = 0x00000001 r9 = 0x00000000 r10 = 0x44160040 fp = 0x00000001 20:03:54 INFO - sp = 0xbead9740 pc = 0x40e2b78b 20:03:54 INFO - Found by: call frame info 20:03:54 INFO - 2 libxul.so!mozilla::layers::ShadowLayerForwarder::~ShadowLayerForwarder [ShadowLayers.cpp:184bbe9eacf4 : 184 + 0x5] 20:03:54 INFO - r4 = 0x446856a0 r5 = 0x44685700 r6 = 0x446856a0 r7 = 0x00000000 20:03:54 INFO - r8 = 0x00000001 r9 = 0x00000000 r10 = 0x44160040 fp = 0x00000001 20:03:54 INFO - sp = 0xbead9750 pc = 0x40e2b7eb 20:03:54 INFO - Found by: call frame info 20:03:54 INFO - 3 libxul.so!mozilla::layers::ShadowLayerForwarder::~ShadowLayerForwarder [ShadowLayers.cpp:184bbe9eacf4 : 184 + 0x3] 20:03:54 INFO - r4 = 0x446856a0 r5 = 0x446856a4 r6 = 0x446856a0 r7 = 0x00000000 20:03:54 INFO - r8 = 0x00000001 r9 = 0x00000000 r10 = 0x44160040 fp = 0x00000001 20:03:54 INFO - sp = 0xbead9768 pc = 0x40e2b809 20:03:54 INFO - Found by: call frame info 20:03:54 INFO - 4 libxul.so!mozilla::AtomicRefCountedWithFinalize<mozilla::layers::ISurfaceAllocator>::Release() [AtomicRefCountedWithFinalize.h : 65 + 0x9] 20:03:54 INFO - r4 = 0x00000001 r5 = 0x446856a4 r6 = 0x446856a0 r7 = 0x00000000 20:03:54 INFO - r8 = 0x00000001 r9 = 0x00000000 r10 = 0x44160040 fp = 0x00000001 20:03:54 INFO - sp = 0xbead9770 pc = 0x40e059d1 20:03:54 INFO - Found by: call frame info 20:03:54 INFO - 5 libxul.so!mozilla::layers::TextureChild::~TextureChild [RefPtr.h : 301 + 0x5] 20:03:54 INFO - r4 = 0x44625a40 r5 = 0x00000000 r6 = 0x00000000 r7 = 0x00000000 20:03:54 INFO - r8 = 0x00000001 r9 = 0x00000000 r10 = 0x44160040 fp = 0x00000001 20:03:54 INFO - sp = 0xbead9798 pc = 0x40e18c13 20:03:54 INFO - Found by: call frame info etc.

Oh, and somewhat well-hidden in the log (or is it even in the log? tbpl shows it, anyway) is the: Assertion failure: mUsedShmems.empty(), at ../../../gecko/gfx/layers/ipc/ISurfaceAllocator.cpp:53

So far this is looking like a regression from bug 1052240, i.e., this push: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?changeset=2dd8e4e95c55 though I triggered a few *more* retriggers on the previous push.

I just added tests. Maybe :nical knows more about this assert?

This is a dup of bug 1016538.
