FWIW, and this may be completely unrelated, but I was getting SEGVs in
authswitch.c using auth_perl_new_user_pass. It was happening here,

(gdb) bt
#0  0x40186b00 in strdup () from /lib/libc.so.6
#1  0x804f652 in authcontext_new (uid=8, gid=0, mboxdrv=0x80664ca "",
    mailbox=0x0, home=0x81d0c58 "/var/spool/mail",
    domain=0x5 <Address 0x5 out of bounds>) at authswitch.c:215
#2  0x804ed1c in auth_perl_new_user_pass (
    user=0x81e22b0 "paul@realprogrammers.com", pass=0x80dcf48 "4321")
    at auth_perl.c:331

It turns out it was because I was returning a perl hash that was
frightening it in ways I haven't yet looked into (this was about
20mins ago).

One thing that might help you is to do a backtrace as above. Invoke "gdb
tpop3d core" and type "backtrace" or "bt". Ensure you're in a position
to write core files with (with bash at least) ulimit -c unlimited.

HTH,
Paul
