--- Comment #3 from Reini Urban <rur...@x-ray.at> ---
This ticket can be closed, not a bug.
My test script finished after some hours of grinding,
which tested all of the 992 returns_nonnull annotated functions in parrot.
Disabling returns_nonnull on one function made it work.
I've checked the assembly.
It was Parrot_cx_check_scheduler(), which had a wrong
if (Parrot_cx_check_scheduler(...) == 0)
check, and consequently this branch was removed by gcc.
So it's really a missed clang and msvc dead-code removal opportunity.
