I'm not clear on what exactly you're doing to get debugging in there, or why you're using an overlay to do it. Try this: CFLAGS="-ggdb3 -pipe" FEATURES="nostrip" emerge xorg-server

Guess it works so too like u mentioned. Now the output is following in gdb: Starting program: /usr/bin/X Program received signal SIGSEGV, Segmentation fault. 0x081f9b6b in ConvertAddr (saddr=0x0, len=0xbfaf1764, addr=0xbfaf1760) at access.c:1861 1861 access.c: Datei oder Verzeichnis nicht gefunden. in access.c (gdb) Any suggestions? best regards

I disabled irda0 and teql0 to see it it works and there it works. Hope this helps a little bit. best regards
Are those devices are properly configured and functioning at the time of crash? And after the crash?

Alright, well, I think it's fairly safe to say this is an upstream problem. File a bug at https://bugs.freedesktop.org and post the link here. Thanks :)
Added Bug Report at freedesktop.org. https://bugs.freedesktop.org/show_bug.cgi?id=5068 best regards
Has this been fixed in more recent versions?
Not yet - a patch exists but acording to spyderous its now! fixed in cvs upstream - i cant confirm this, but we'll see in a few days when a new release will be there. kind regards
That patch is in xorg-server 1.0.2.
