(gdb) cont
Continuing.
Program received signal SIGSEGV, Segmentation fault.
0xfef33084 in strlen () from /usr/lib/libc.so.1
(gdb) bt
#0 0xfef33084 in strlen () from /usr/lib/libc.so.1

(gdb) quit
The program is running. Quit anyway (and detach it)? (y or n) y
Detaching from program: /opt/tpop3d-1.5.3/sbin/tpop3d LWP 1
(Process is gone afterwards.)
Hmmm.... Is this any different from the output based on the core dump?
Full output at: http://www.scsy.de/~mas/debug/tpop3d/gdb-out1.txt (That is,
unless I've made a mistake when copying this from my xterm.)
Thanks a lot for your assistance, Chris.
