Xorg segfaults when using Xevie, after calling XNextEvent(). xorg-6.8.2-r6 suffers from this problem. I recently moved to the cvs ebuilds, and it seemd to be corrected on 6.8.99.15-r4, but reapeared on 7.0.0_rc4 (the new "modular X"). Reproducible: Always Steps to Reproduce: 1. Activate the Xevie extension on xorg.conf 2. Make a simple program using xevie or use the "demo" availiable on freedesktop.org 3. Make it call XNextEvent() when appropriate 4. Compile and run 5. Comment out the XNextEvent() call 6. Compile and run Actual Results: The version calling XNextEvent() crashes givig us "Segmentation fault". The other version runs normally (without intercepting the events of course..) Expected Results: The program shouldn't be crashing on that call. Xorg's Xevie extension isn't working in gentoo's xorg. I googled around and found no reference to this bug whatsoever. It may be because it's only used by devs right now.. I suspect the problem may be related to gentoo's "modular X", but it may as well be a xorg bug. Please "upstream-it" in such case.

Did you try any other versions of modular in between 6.8.99.15 and the latest 7.0?
No, I haven't. I only switched to modular when the "cvs" (hard masked) version went modular..
Well, we've had a masked modular version in the tree since rc0, which was ~2 months ago, and there have been 3 different modular releases. Was just wondering how long you had been using modular.
Can you get a useful backtrace out of the app that segfaults?
I'm sorry but it works perfectly now.. I'm using xorg-x11-7.0.0 and libxevie-1.0.0. I thought it was already solved.. :/ I'm switching it to "fixed". I guess I should have done that before.. Thanks anyway!
