Running the latest stable apache on gentoo (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.
