The following valid code snippet triggers an ICE since GCC 4.1.0:

======================================
int foo()
{
  L: return __builtin_expect ((__SIZE_TYPE__)&&L, 0);
}
======================================

bug.c: In function 'foo':
bug.c:3: internal compiler error: tree check: expected tree that contains 'decl
with visibility' structure, have 'label_decl' in fold_builtin_expect, at
builtins.c:7327
Please submit a full bug report, [etc.]
