bug#25712: 24.3; core dump

[Guy Charbonneau]

Sorry, I don’t know where to get the source tree for emacs so I can’t troubleshoot.

This segv has happened to me about 10 times over the last two weeks.

I’m running multiple frames, each with one buffers with a shell. In one of them running a perl -w script.pl that sometimes gets stuck parsing some source code in a tight loop.

It seems to happen when I switch between frames.

 

If Emacs crashed, and you have the Emacs process in the gdb debugger,

please include the output from the following gdb commands:

    `bt full' and `xbacktrace'.

For information about debugging Emacs, please read the file

/usr/share/emacs/24.3/etc/DEBUG.
