I still don't understand the bug but it seems to be related to the code inside
the   POINTERS_EXTEND_UNSIGNED ifdef in function.c.  If I comment this out
things compile, if I leave it in and put a call to verify_flow_info() before the
return 1 in that if block then verify_flow_info will cause an abort.  A call
just before the if statement will not abort so this appears to be the code that
is corrupting the cfg.

Hmm, we are putting code after the loop and after function end, I don't know why.
