If this is reliably reproducible, can you try doing the following:
Ensure you have an smbd with debug symbols, then add the line:
panic action = "/bin/sleep 90000"
to the [global] section of your smb.conf. Then reproduce the
problem. The crashed smbd will be stuck waiting for the sleep
to exit, it will be the parent process of the sleep process.
Attach to it with gdb and then type "bt" to get a full stack
backtrace. This looks to me a bit like a null pointer indirection
which we may have fixed in the current 3.2.x code in the git tree
(but I can't promise that until I see the backtrace).
