depends on your OS. Current versions of Linux don't do coredumps on
processes that have changed uid. This is a kernel bug, and will
hopefully be fixed, the right fix is to set RLIMIT_CORE to 0 when a
uid change is made and allow the app to up it again.

hmmm, or maybe the problme is the exit() in smb_panic() ? hmmm, I'll
change it to abort().

meanwhile, use "panic action" instead. Mine is set to:

  panic action = /usr/bin/X11/xterm -display :0 -e gdb /proc/%d/exe %d
