  sudo apt-get install openssl

I'm actually having a little trouble turning the core file into a stack
trace.

  gdb core
  "[long path]/core": not in executable format: File format not recognized"

I tried compiling server.ss with mzc and doing gdb and running gdb
compiles/server.zo core but that failed the same way.  What is the right way
to do this?

SIGSEGV fault on 0xe00000000
Aborted


Thanks for the fast feedback on this, Jay.  No rush on it for now,
though...I'm walking out the door and won't be around until this evening.
