Running the latest stable apache (2.2.14-r1) and xdebug (2.0.5) results in a segfault every time I access any php page. Apache's error log shows: [notice] child pid 24697 exit signal Segmentation fault (11) This happens even on simple script which just calls phpinfo(); I've set apache to 1 thread and caught a backtrace with gdb: Program received signal SIGSEGV, Segmentation fault.

Sure, I've recompiled apache, php and xdebug with -ggdb and FEATURES=nostrip. Here you go: Program received signal SIGSEGV, Segmentation fault.

Upstream bug report: http://bugs.xdebug.org/view.php?id=554 The crash is solved in SVN 3241 and maybe in the xdebug 2.1 betas/RCs. So any xdebug-2.1 ebuild will probably solve this bug, too.
I've just added 2.0.1_rc1 to the tree. I don't get any errors with this version. Thanks for reporting and taking this upstream. Please reopen if you still have issues.
I would like to reopen that bug - but am not allowed to. xdebug-client has been bumped to 2.1.0_rc1, but the problem lies within "dev-php5/xdebug"! Also, the correct version is 2.1.0_rc1 not 2.0.1_rc1 as stated in the last comment. The issue is not solved. Apache still crashes with PHP and xdebug enabled, because xdebug is still at version 2.0.5.
My bad. We actually have both dev-php5/xdebug and dev-php/xdebug-client in our overlay and I just committed dev-php/xdebug-client. The version in the bug was a typo, I really did 2.1.0_rc1 :-) And now dev-php5/xdebug, too.
Yes - that was it. Works great now.
