Comment (by tom):

 I don't think this is the issue, but if nothing else is leading to it, it
 might be worth throwing in a

 {{{
 if(!mD3DCompilerModule)
   __builtin_trap();
 }}}

 (per
 https://trac.torproject.org/projects/tor/wiki/doc/TorBrowser/Hacking/DebuggingOnWindows#Breakingwherewewanttobreak)

 at
 https://searchfox.org/mozilla-
 central/rev/e126996d9b0a3d7653de205898517f4f5b632e7f/gfx/angle/checkout/src/libANGLE/renderer/d3d/HLSLCompiler.cpp#139
 and

 central/rev/e126996d9b0a3d7653de205898517f4f5b632e7f/gfx/gl/GLLibraryEGL.cpp#417

 just to be certain out d3dcompiler dll is getting loaded... I had seen
 intermittent test failures (on a mingw build) where it wasn't but never
 could figure out why.
