Looks like it might be a bug in libc, can you provide a full stack trace (with debugging symbols) so that we can see what path causes the crash ?
howto do that? Install debug symbols but then, for a daemon? Start manually etc?
An easy way is to set: panic action = "/bin/sleep 90000" in smb.conf This whould make samba halt for 90000 seconds when it crashes. when that happen attach gdb to the process and use the commend "bt" to obtain the stack trace. Attach the output to the bug report.
