Smaller one:

[hjl@gnu-6 tmp]$ cat y.c
extern void abort ();
int
__attribute__ ((__noinline__))
foo (unsigned int tls_type)
{
  if (! (tls_type == 4 || (tls_type == 6))
      || (tls_type == 2 || (tls_type == 6)))
    return 1;
  return -1;
}
int
main ()
{
  if (foo (6) != 1)
    abort ();
  return 0;
}
[hjl@gnu-6 tmp]$ /usr/gcc-4.6/bin/gcc -O2 y.c      
[hjl@gnu-6 tmp]$ ./a.out 
Aborted
[hjl@gnu-6 tmp]$
