Can you install with debug symbols, and then add the line:

panic action = /bin/sleep 9999999

to the [global] section of your smb.conf. Once it crashes,
this will cause the crashed process to stay around waiting
for the sleep process to finish. Find the crashed process
using ps (it'll be the parent of the "sleep") then attach
to it using gdb - then type "bt" which will give a full
backtrace with symbols - allowing us to track it down
much more easily.

Thanks !

Jeremy.
