Go to the directory where you have the Emacs sources (assuming you have them on your system), then type at the shell prompt $ gdb emacs When you get to the "(gdb)" prompt, type "run". Emacs should start as usual, and then do whatever you need to reproduce the problem. When Emacs crashes, GDB will kick in and show its "(gdb)" prompt where you started it. Then type at GDB's prompt: thread apply all bt This will produce backtraces of all the threads in the Emacs process. Post the output here.
