Summary0000173: xdebug segfaults using SPL
Description

Xdebug segfaults using SPL ArrayIterator.

Unloading xdebug make things work as expected.

reproduce code :

After a while , I found the shortest way to reproduce it ;-)

php -d xdebug.auto_trace=1 -d xdebug.collect_return=1 -d xdebug.collect_params=1 -r 'new ArrayIterator(NULL);'

Im using loastest PHP 5.1 cvs and latest xdebug CVS.
