Ah. I see what goes on then. The new logic assumes that GOMP_barrier does not
change shrd (which is a local non-address-taken static variable in main,
accessed from the OMP clone main.omp_fn.0). This is of course true, but
nothing
in GCC knows about threads - instead we rely on the builtins to act as
optimization barriers.
The patch breaks this assumption.
I will revert the broken part for now.
