[Bug c++/34610] New: [4.3 regression] ICE with "-fprofile-arcs -fopenmp"

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following valid code snippet triggers an ICE on mainline when compiled
with "-fprofile-arcs -fopenmp":

=======================================================
void foo()
{
#pragma omp for
  for (int i=0; i<10; ++i)
    ;
}
=======================================================

bug.cc: In function 'void foo()':
bug.cc:3: internal compiler error: in expand_omp_for_static_nochunk, at
omp-low.c:2916
Please submit a full bug report, [etc.]

If I add "schedule(dynamic)", I get a slightly different error:

=======================================================
void foo()
{
#pragma omp for schedule(dynamic)
  for (int i=0; i<10; ++i)
    ;
}
=======================================================

bug.cc: In function 'void foo()':
bug.cc:3: internal compiler error: in expand_omp_for_generic, at omp-low.c:2714
Please submit a full bug report, [etc.]
