Please compile Emacs with debug information and without optimizations,
then run it under a debugger, and when it crashes, please post the
full backtrace from the debugger, including the Lisp backtrace
(produced by GDB automatically if you source the .gdbinit file that
comes with Emacs).

Also, you didn't post the information about your build that is
normally collected by "M-x report-emacs-bug"; please post that, it's
important for the analysis of the possible reasons.

Thanks.
