Comment (by tom):

 I passed that to Jacek; and he thinks that should be fixed as well; so we
 may need another bump - although I'm not sure if/how thee values are
 actually used.

 Thank you!

 This looks good to me. I cherry-picked this patch as commit

 gl or anyone else that hits this problem: does it get solved by

 https://people.torproject.org/~gk/testbuilds/torbrowser-install-win64-tbb-

 ? (You might need to restart Tor Browser due to things like #28405)

 The bundle got built with tom's mingw-w64 fix, fwiw.

 Thanks cypherpunk; that's probably it. I'm sending in some trials on
 TaskCluster to see if that solves my 8-month old error. I pinged Jacek
 about whether MinGW should update or we should override.

 Nope:
 https://github.com/apitrace/dxsdk/blob/master/Include/d3dcompiler.h#L18

 Since all this seems to be related to DirectX; I suppose getting some info
 about that might be helpful.

 Start -> Run -> dxdiag will get diagnostic information. At a minimum I'd
 say go to the Display page and copy that info (either with a screenshot,
 or save the info to a text file and copy it out.)

 > ERR: ensureInitialized(141): D3D compiler module not found.

 I guess that's the reason for the trouble you are seeing. The relevant
 code around it is:
 {{{
 #if !defined(ANGLE_ENABLE_WINDOWS_STORE)
 #if defined(ANGLE_PRELOADED_D3DCOMPILER_MODULE_NAMES)
 // Find a D3DCompiler module that had already been loaded based on a
 predefined list of versions.
 static const char *d3dCompilerNames[] =
 ANGLE_PRELOADED_D3DCOMPILER_MODULE_NAMES;

 for (size_t i = 0; i < ArraySize(d3dCompilerNames); ++i)
 {
 if (GetModuleHandleExA(0, d3dCompilerNames[i],
 ))
 {
 break;
 }
 }
 #endif  // ANGLE_PRELOADED_D3DCOMPILER_MODULE_NAMES

 if (!mD3DCompilerModule)
 {
 // Load the version of the D3DCompiler DLL associated with the
 Direct3D version ANGLE was built with.
 mD3DCompilerModule = LoadLibrary(D3DCOMPILER_DLL);
 }

 if (!mD3DCompilerModule)
 {
 ERR() << "D3D compiler module not found.";
 return gl::OutOfMemory() << "D3D compiler module not found.";
 }

 mD3DCompileFunc =
 reinterpret_cast(GetProcAddress(mD3DCompilerModule,
 "D3DCompile"));
 ASSERT(mD3DCompileFunc);

 mD3DDisassembleFunc =
 reinterpret_cast(GetProcAddress(mD3DCompilerModule,
 "D3DDisassemble"));
 ASSERT(mD3DDisassembleFunc);

 #else
 // D3D Shader compiler is linked already into this module, so the
 export
 // can be directly assigned.
 mD3DCompilerModule = nullptr;
 mD3DCompileFunc = reinterpret_cast(D3DCompile);
 mD3DDisassembleFunc =
 reinterpret_cast(D3DDisassemble);
 #endif
 }}}
 in HLSLCompiler.cpp

 We are not defining `ANGLE_PRELOADED_D3DCOMPILER_MODULE_NAMES` in
 https://dxr.mozilla.org/mozilla-esr60/source/gfx/angle/update-
 angle.py#257. But I wonder where `D3DCOMPILER_DLL` is supposed to come
 from in our case. From `d3dcompiler.rs`??

Comment (by gl):

 not sure how to test it, but here is what I've got:
 it crashed during first start as expected;
 it got stuck at connect to tor phase during second and third start due to
 #28405 and #28614;
 it connected and "crashed" from webgl as expected during fourth start;
 nothing in debug logs;
 then I set e10s off and got

 Hey, could you test a debug build to gather more information about what is
 going on?

 https://people.torproject.org/~gk/testbuilds/torbrowser-install-win64-tbb-
 nightly_debug_en-US.exe
 https://people.torproject.org/~gk/testbuilds/torbrowser-install-win64-tbb-
 nightly_debug_en-US.exe.asc

 It will crash during first start (which is #28875) but should work
 afterwards. It would be interesting to see if we hit any assertions before
 crashing.

 I tried to create debug builds to help narrowing this down but that only
 resulted in sadness and #28875. :(

New description:

 On our blog one user noted
 (https://blog.torproject.org/comment/278911#comment-278911) that
 https://browserleaks.com/webgl is crashing their tab reliably using 8.5a6
 in the 64bit flavor for Windows. This does not happen with the 32bit
 variant. And neither does this happen with vanilla Firfox 60.4.0esr.

 It seems that a bare Firefox compiled our way without any Tor Browser
 patches is crashing as well. Thus, I wonder whether we hit a GCC bug or
 something that is only affecting some 64bit system. Mysterious.
