Rational for bug report:

   * If the debugger gets a fatal signal, for any input whatever, that
     is a GDB bug.  Reliable debuggers never crash.

Version: 4.5
Machine: Sparc ipc OS 4.1.1
Compiler: gcc-1.40?
Program: framemaker 3.0X (no symbols)

Description: gdb core dumped when trying to do a backtrace on a core
file that has no symbols.

Session:

      I started gdb with framemaker as the input executable.
      I did a 'core core' to bring in the core file.
      I finally tried to get the backtrace information.
