[reichelt at gcc dot gnu dot org]

The following valid code snippet triggers an ICE since GCC 4.1.0 when compiled
with "-O2":

================================
void bar();

void foo(int i)
{
  __complex__ int k = 0;

  if (i)
    k = 1;

  for (i = 0; i < 1; ++i)
    ;

  if (k)
    bar();
}
================================

bug.c: In function 'foo':
bug.c:4: internal compiler error: tree check: expected value_handle, have
ssa_name in bitmap_set_contains_value, at tree-ssa-pre.c:744
