Description Jonathan Kamens 2005-12-01 19:07:28 UTC 
With emacs-21.4-10, load a file into emacs with C-x C-f, type a few 
characters, then type C-x k RET, and emacs will coredump.

It's coredumping at doprint.c:249.  The cause of the coredump is, I believe 
the gcc problem documented in bug 174728.
Comment 1 Jonathan Kamens 2005-12-01 22:00:10 UTC 
The problem is the -fstack-protector that's being passed to the emacs build, 
presumably from RPM.  If you filter that option from CFLAGS and rebuild emacs, 
it doesn't crash anymore when the above scenario is executed.
Comment 2 Paul Dickson 2005-12-02 10:36:10 UTC 
I hit this bug too.
Comment 3 Jens Petersen 2005-12-12 07:58:35 UTC 
Is this still reproducible with current rawhide?

I don't see it with "emacs -nw" nor when running emacs-x over ssh currently.

Comment 5 Jonathan Kamens 2005-12-12 14:48:58 UTC 
This problem persists for me in emacs-21.4-10.1 when running emacs -nw.
Comment 6 Paul Dickson 2005-12-12 19:22:17 UTC 
I still have problem with emacs-21.4-10.1, with and without the -nw argument.
Comment 7 Jens Petersen 2005-12-13 04:23:30 UTC 
rawhide-i386?  Sorry I only tested on x86_64...
Comment 8 Jonathan Kamens 2005-12-13 13:51:55 UTC 
Yes, i386.
Comment 9 Jens Petersen 2005-12-14 02:38:21 UTC 
Thanks.  Reproduced on x86_64 console with emacs.i386 too.
Comment 10 Jens Petersen 2005-12-14 08:05:29 UTC 
[CCing Jakub and redhat-rpm-config owner]

Thanks, Jonathan, for the report and fix.
Should be in emacs-21.4-11.
Comment 11 Jens Petersen 2006-03-28 03:57:02 UTC 
Fix should be in FC5.
