I get a segfault when using phpunit 3.3.10 and xdebug 2.0.4 on php 5.2.8 to get code coverage information in a project of mine. I'll try to gather information.

TagsNo tags attached.

crash.php that has to be run:
function hdl(){}
xdebug_start_code_coverage(XDEBUG_CC_UNUSED | XDEBUG_CC_DEAD_CODE);
require_once 'test.php';

class DB
function f()
if (true) {}
$obj =& new a;
