The following valid testcase triggers an ICE since GCC 4.2.0 when compiled
with "-fmudflap":

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

jmp_buf buf;

void foo(volatile char* p)
{
  if (__builtin_setjmp(buf))
    *p;
}
====================================

bug.c: In function 'foo':
bug.c:6: error: control flow in the middle of basic block 11
bug.c:6: error: control flow in the middle of basic block 11
bug.c:6: internal compiler error: verify_flow_info failed
Please submit a full bug report, [etc.]
