You won't get a core if you're using UserID, since some OSes now refuse to
dump cores if setuid() is called. Is that the case here?
Yes.
I have reports of two different crash bugs that appeared in the 2.5.x
line. Thus, 2.5.4 will come out tomorrow with fixes for them. I'd like
to be sure that your problem is one of those though, so getting a stack
trace would be ideal. Can you run your filter inside gdb?
Sigh, so I ran it as root to get a core dump and recompiled with "-g -O"
to get symbols. Yea, I got a core dump. Attached is the gdb backtrace
and some poking around in the data at the crash site. memcpy is unhappy
with the data handed to it. Hope this helps.
