Subject: bug#3659: FW: 23.0.95; crash on set-frame-font
Date: Fri, 24 Jul 2009 09:31:08 +0100 [thread overview]
Message-ID: <63C2A154B1708946B60726AFDBA00AC00676D571@ukmailemea01.misys.global.ad> (raw)
In-Reply-To: <E1MU9G3-0008Hv-HO@etlken>
With a CFLAGS=-g version of yesterday's trunk, the crash happens in a
different place (it aborts semi-cleanly). This is true of the
2009-05-20 version as well:

(gdb)
With a CFLAGS="-g -O2" version I do not get a crash anymore.
So: -g aborts in 2009-05-22 and 2009-07-23 versions
But: -g -O2 crashes in 2009-05-22 and appears ok in 2009-07-23 versions
What to do?

Ummm, the content of this structure is completely broken, or
"charset" points incorrect memory.

It's a bug of old .gdbinit, and is now fixed both in the
trunk and EMACS_23_1_RC branch. It seems that you are not
using the latest emacs code, but as we already found the
culprit change, we can debug using the latest code. Please
recompile the latest code of the trunk or branch with
% make CFLAGS=-g clean all
When you get segfault with that code, please show me the
backtrace again, and the results of these commands.
(gdb) up 2 ;; go up to the function xfont_list_pattern
