bug#13846: 24.3.50; segmentation fault

[Paul Eggert]

Thanks for the bug report.  Can you please try building
Emacs without optimization, and generating a backtrace for that?
Assuming that the exception is in XPutPixel, it'd be helpful
to know the values of x, y, etc. for that call to XPutPixel.

Also, is the .jpg.psd file in question something that you can
share with us, e.g., by attaching it in followup email?

earlier backtrace is produced with emacs built with CFALGS="-g -00". should I
build something differently.

Unfortunately, I can't.

If needed, I can send psd file to you instead (off list).

No, thanks, it's already unoptimized.

That might help me reproduce the problem, yes.

Sent. could you confirm.?

bit off topic..
I sent mail using gnus and when I try to enter my sent mail group (in gnus),
emacs is being crashed :o , I am not sure why gnus needs to look into mime
attachments while entering into a group. 

Thanks.,

Got it, thanks.  This let me reproduce the bug easily, I installed
a patch into the trunk as bzr 111937, and I'm marking this as done.

Was the crash due to this image?  If so, the bug should be fixed now;
if not, please open another bug report for Gnus.  I don't know why
Gnus needs to look into mime attachments, but presumably we can look
into that if the bug persists.

I can confirm that the bug is fixed.

Yes, It is also the same problem and is fixed with your patch.

Thank you very much.,
