This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. class_name and call_type were re-used in a loop when they should have been cleared on every iteration. Test runs correctly now.
