The following valid code snippet triggers an ICE since GCC 4.2.0
when compiled with "-O":

=========================================
#include <setjmp.h>

jmp_buf buf;

int foo()
{
  __complex__ int i = 0;

  if (__builtin_setjmp(buf))
  {
    i = 1;
    bar();
  }

  return i == 0;
}
=========================================

 Corrupt SSA across abnormal edge BB2->BB7
Argument 0 (0) is not an SSA_NAME.
bug.c: In function 'foo':
bug.c:6: internal compiler error: SSA corruption
Please submit a full bug report, [etc.]

Maybe related to PR35314.
