A segfault is always a bug (or bad ram/hardware).

When does this occur? What is happending when it crashes? Can you rebuild
wu-ftpd with debugging symbols (set CFLAGS to include -ggdb and NOT any -O
optimizations)? Then Start the daemon, and attach to the process with gdb
(attach <pid>). See where it crashes.

If nothing else get it to dump a core (check your limits for
corefilesize). Then run gdb on the core and do a backtrace.
