[Bug middle-end/37060] [4.3/4.4 regression] Bogus __builtin___memcpy_chk overflow warning


------- Comment #2 from rguenth at gcc dot gnu dot org  2008-08-08 15:43 -------
We fail to see that the len == 16 case cannot happen in the second if (), more
specifically we fail to jump-thread because of the twisted CFG.
