    A crash pretty much always indicates a bug. If you can reproduce the crashing behavior, then try to provide a recipe to reproduce it, preferably starting from emacs -Q (no init file), and include the recipe in a bug report: M-x report-emacs-bug. – Drew Sep 7 '17 at 15:03
  • I can count with fingers on one hand how many times I have been able to resolve a crash without building Emacs from source and running it under gdb. Unless you get extremely lucky, you will not be able to make any intelligent determination as to the true cause of a crash. You can, of course, submit a bug report to the Emacs team without a gdb backtrace and let them try and figure it out. If the Emacs team cannot reproduce the issue, then there is not much they can do to help. A detailed backtrace will greatly assist the Emacs team in working on the bug report. – lawlist Sep 7 '17 at 17:31
