If you can reproduce the crash, please start Emacs from GDB to begin
with.  That's because the backtrace you sent shows that the top-level
exception handler was called, which means the real locus of the
problem is not shown in the backtrace.  When Emacs is started from the
debugger, the debugger gets control before the top-level exception
handler, so you should be able to produce a much more informative
backtrace.

Please also show a recipe for reproducing the problem.

Thanks.
