From: peder <at> klingenberg.no (Peder O. Klingenberg) To: 17125 <at> debbugs.gnu.org Subject: Re: bug#17125: Acknowledgement (24.4.50; daemon mode: closing X client frame exits entire emacs) Date: Tue, 01 Apr 2014 13:35:24 +0200
The server process exits with a SIGSEGV and a core dump. The error
seems to happen in font_clear_cache, maybe related to the changes
described in bug #16069
Attaching a gdb to the server process before starting the emacsclient
allowed me to capture the following:
Program received signal SIGSEGV, Segmentation fault.

Looking at the local i in stack frame #2 above, it seems way out of
