I have had a number of problems with recent updates of emacs 23 segmentation faulting on me when trying to use the font backend and antialiased fonts. I am unsure exactly what is causing the problem. It works fine when I compile it on a rather freshly updated debian system but the problem hits when trying to build and run on my primary workstation which is a SuSE SLED 10 SP1 system with some additional software installed. In particular this system doesn't really have gtk+ 2.0 and fontconfig claims to be version 2.3.94 and I am enabling the font backend and is trying to use fancy anti-aliased fonts. The problem hits in src/ftfont.c (ftfont_lookup_cache). The attached patch seems to alleviate the problem, at least to the point where emacs stops segmentation faulting. Even if the problem ultimately is a unfortunate combination of old libraries, I believe the patch is innocent enough to warrant inclusion. More information can be provided if you like. -- Christian
