You need to switch to the right thread, usually thread 1.  Can you
repeat the attempt, and produce a backtrace?  When Emacs shows the
abort dialog, and you attach the debugger, do this:

 (gdb) info threads
 (gdb) thread 1
 (gdb) bt

If thread 1 doesn't show a useful backtrace, do the same with thread 2
etc.

TIA
