OK this is a strange one; I'm just submittingon the off chance some gentoo dev has heard of this or has a miraculous explanation. Whenever I expand or collapse a gtktree view by clicking on the little "trangle of disclosure" X immediately crashes. Howerver, this only happens if I log in through kdm or xdm. (!) If I log in via "startx" everything works perfectly. This has happened with porthole, gconf-editor, gaim, and gtk-demo at least. All exactly the same crash immediately after hovering over a little tree view triangle. As far as I can tell, the apps still work perfectly well otherwise (I stll use gaim all the time, just have to make sure not to hit the triangles) Unfortunately, the xorg logs have no useful info whatsoever, and straces of the offending apps are likewise useless (theyjust end with a read from the X server usually). Trying to attach strace or gdb to X itself has not been successful so far at all. The only difference can note for sure is that kdm, etc starts X with "X" and has an "-auth" argument, while startx starts X with "xnit" and ha no such argument. I have recompiled gtk+ and all of it's deps. I am using Xorg. Also, this only happens on my laptop (P4, ATI drivers) and not my desktop (AMD, nvidia) and both have essentially identical CFLAGS, toolchains, and kernels otherwise. I know its a long show but any useful info or even suggestions about how to obtain better debugging info would be appreciated.

well first sanitize your CFLAGS and recompile stuff.. the fact that you yourself can't reproduce it sais a lot. While at it, recompile with debugging support so if it keeps crashing (which i don't expect) you can get some decent output.
I recompiled gtk+ with "CFLAGS="-pipe" and the problem persists. xorg-x11 already strips it's own flags: # The next command strips CFLAGS and CXXFLAGS from nearly all flags. If # you do not like it, comment it, but do not bugreport if you run into # problems. (I haven't commented strip-flags out.) I don't think compiling in debugging symbols would be of use for anything oher than xorg-x11 itself. straces on the offending apps just show the unix socket calls to X, but it is X itself that is crashing, not the apps. On the other hand, I have poked around but never been able to find a core file for X. Do you know where they get written or if I have to configure something to get them dumped?
OK, re-emerging glibc (with the same CFLAGS as I had orginally) fixed.
