What might help is to change the code in safe_strcpy_fn
to call smb_panic on this detection, and then to reproduce
the error with the relevent panic action set in smb.conf.
If you get me a backtrace I can see if we've already
fixed this (most string handling code is massively
different in 3.2.x from 3.0.x).
