Anoter testcase that ICEs even with -O2 -fopenmp:
/* { dg-do compile } */
/* { dg-options -O2 -fopenmp } */

void bar (int, int);
void
foo (int *a)
{
  int i;
  for (i = 0; i  8; i++)
#pragma omp task
if (a[i])
  {
int j, k;
for (j = 0; j  10; j++)
  for (k = 0; k  8; k++)
bar (j, k);
for (k = 0; k  12; k++)
  bar (-1, k);
__builtin_abort ();
  }
}

Log:
PR middle-end/58551
* tree-cfg.c (move_sese_region_to_fn): Also move loops that
are children of outermost saved_cfun's loop, and set it up to
be moved to dest_cfun's outermost loop.  Fix up num_nodes adjustments
if loop != loop0 and SESE region contains bbs that belong to loop0.

* c-c++-common/gomp/pr58551.c: New test.
