--- Comment #2 from Jakub Jelinek ---
Reduced testcase:
void bar (void *);
void
foo (int x)
{
struct S { int a[x]; int b; } s;
#pragma omp parallel for
for (int i = 0; i < 10; i++)
bar ();
}
We don't really support variable length structures/unions in OpenMP/OpenACC
lowering/expansion, and I don't see why we should spend time on that, variable
length structures/unions just shouldn't be used in C (they are already invalid
in C++ and not present in Fortran either), I think that extension exists just
because Ada needs to support that. Though Ada on the other side doesn't
support OpenMP/OpenACC.
So, I think we should just sorry if something attempts to privatize/map
variable length structure/union; making it shared should be fine.
