            Bug ID: 106449
           Summary: ICE in #pragma omp parallel for simd
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: sandra at gcc dot gnu.org
  Target Milestone: ---

Test case is derived from c-c++-common/gomp/loop-8.c, with "simd" added:

void
foo (void)
{
  int a[1024];
  int *p, *q;
  #pragma omp parallel for simd collapse(2)
  for (p = &a[0]; p < &a[512]; p++)
    for (q = p + 64; q < p + 128; q++)
      ;
}

$ x86_64-none-linux-gnu-gcc -fopenmp loop-8.c
during GIMPLE pass: ompexp
loop-8.c: In function 'foo':
loop-8.c:6:11: internal compiler error: in build2, at tree.cc:5023
