Summary0000321: PHP segfault with xdebug 2.0.1
Description

As you know PHPUnit 3.x uses xdebug for code coverage.
Xdebug 2.0.0 works perfectly for such purposes, but we started to get segmentation faults after I've installed xdebug 2.0.1 version instead of 2.0.0.

Yes, seems to be (partly) fixed ... Unit Tests run fine ... but now we get a segfault when PHPUnit wants to access the coverage data ... still need to get a core file ... will attach it soon ...
