I would say that's not a valid stack trace.  There hasn't been a
change made to that file since October of last year, and the crash is
apparently recent; also, line 1250 in that file doesn't look like
something that can crash.  I would guess that you're using an
executable which doesn't match the core dump, or perhaps that you
don't have complete debug symbols.

You really need the same compiler flags, configure opts and preferably much the same compiler. Similar or same C library etc. 

Can't we get the executables from Travis CI or from whoever produced the core? Or get them to obtain a bt ?
