Comment # 1 on bug 1087136 from Michal Srb

Few tests inside single test binary are crashing. I am debugging the crash now.
It is not clear to me how could gcc8 cause this - we build llvm in two stages,
first we build clang with gcc and then build everything with that, including
the tests.

The test also crashes when run with distribution's libLLVM5, which was built
using gcc7. So it must be something in the test binary itself.

LLVM6 has the same issue.
