Based on your other message indicating that you're essentially seeing
segfaults in main() in the smbd process, something I've never seen, I'm
more than a little concerned about the accuracy of these backtraces.
Are you using stock libc on this system?  What version of gcc did you
use when recompiling samba for debugging symbols?  Did you use the
Debian packages as a base for this build, or did you use the upstream
tarball -- and if the latter, what options did you pass to ./configure?

The backtraces you've included below do NOT suggest that the binaries
have intact debugging symbols, as several of the functions on the stack
have no names associated with them.  Do you get different results from
gdb (using the default Debian 'panic action' script)?

Cheers,
