If Emacs crashes it's a bug in Emacs (tho it may indeed be triggered by
EDE).  If Emacs hangs, it may be a bug in Emacs or (more commonly) a badly
written regexp that leads to exponential time behavior (or a few other cases
such as improperly using inhibit-quit).  For regexps-misbehavior, we usulyl
need a C backtrace and then we need you to examine which regexp is the
culprit by examining a few C variables using gdb macros like "xtype" and
"xstring".
