This crash happens when I running the new ipc mochitest case added in bug 869869. See try server result in https://tbpl.mozilla.org/?tree=Try&rev=621ad1b3108e.

Shih-Chiang, do you have a stack?

Yes, Cwiiis changed this code recently so perhaps we can offer some assistance.

What does this test-case do? It's worth noting that the Android tiles backend is designed to work with threads and not processes, in case this is changing that? Also worth noting that I'm off for 2 months after tomorrow, but I'll try to help when I have time.

@Cwiiis, this test case is trying to run all the PeerConnection mochitest in a remote iframe, i.e. in content process. Does it means I should skip this IPC test case on Android platform? but we already have DeviceStorage/IndexDB IPC test running on Android platform. @Milan, try server won't let me run testcase on debug build. I'll try buliding up a fennec environment and get the stack.

Is there something causing the iframe to draw in this case where it doesn't in others, perhaps? We should probably have a more robust test for whether non-shm can be used for tiles, currently it's just a define: https://mxr.mozilla.org/mozilla-central/source/gfx/layers/client/TextureClient.cpp#498 An easy way to test if that's the problem is to just change the MOZ_ANDROID_OMTC #ifdef's into #if 0's - that will stop it from taking the non-shm shortcut (note, we need this shortcut for performance reasons atm).

Turning off MOZ_ANDROID_OMTC will crash before executing mochitest, therefore, I cannot tell if comment 6 is the correct direction of analyzing this issue. https://tbpl.mozilla.org/?tree=Try&rev=060d2e884b3d

@cwiiis, Fennec will crash after turning off MOZ_ANDROID_OMTC from mobile/android/confvars.sh. The crash stack is provided in comment 7. Does it give you more clue on this issue?

SChien you won't get a response from Chris for months. He out of the office through the new year. I suggest asking someone else.

@BenWa, can you help check the crash stack in comment 7 since @Cwiiis is on PTO?

I can't work on this without neglecting something else.

@milan, can you help me find someone to take a look at it? I'll disable this test case on Android for now and re-enable it after this bug is resolved.
