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.
