Cameron and Jay,

FYI, it was so weird for me too.
I have not met the failure on llvm/test, but I got sometimes
clang/CodeGen failed.

As far as my investigation;

  - I can see hangup only with "Release" build.
  - I could not reproduce with single-run of the test, (I had to run
entire clang/test/CodeGen then)
  - It might depend on link order, for example, to tweak
TARGETS_TO_BUILD, it appeared and disappeared. XD
  - When I saw hangup, it could be resolved to revert r133708. (and
reprod to reapply it)
   (I found it with bisect-ing)
  - I cannot meet it on ToT, apparently fine. (sigh...)

HTH, ...Takumi
