Hi. I'm running a recent emacs built from git:
https://github.com/emacs-mirror/emacs/commit/6e2a402
I'm on a Debian machine, running the GTK build of emacs. Segfault
recipe:
1. emacs -Q /tmp/feedgnuplot (source attached)
2. M-x cperl-mode
3. C-s last if /^exit/ C-s
Type out the string "last if /^exit/". It may crash while you're
typing it, or it may reach the end of the string in the match on line
431. Hit C-s again after you typed it. If it didn't crash already,
the extra C-s makes it crash.
I haven't done any debugging other than to look at the backtrace.
Relevant chunks:
