Bug 284405 – kwin (build with gcc 4.4.1) crash

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Arne Flagge 2009-09-10 05:44:16 UTC]

I rebuilded my system with gcc 4.4.1 (without any build errors), but now kwin fails to start. I pin point it to kwin, because X starts (I can start twm). Then I also can start kde (with startkde) except of kwin. Because kwin crashes twm is then the window manager. I've tested it with a new user and a blank profile (no .kde), so it is no configuration problem.

Reproducible: Always

Steps to Reproduce:
1. login as user
2. start twm (startx)
3. start kwin (kwin --replace), backtrace below

I tried it again, now of course with kde 4.3.2. And it works without any problems. Marked as fixed (somehow).
