[Crash-utility] sig -g and foreach sig -g

Hello Dave, I think sig -g is quite OK. I have a problem with foreach sig -g. If i use malloc() and free(), it seems to work (may be the algorithmic is OK). I have tryed to use hashing on tgid to control if we have already displayed it. If i use GETBUF() and FREEBUF(), it crashes. May be i don't understant some conditions in using GETBUF() and FREEBUF() ? Thanks for any suggestion.
