Summary: segfaults at method_exists()
-Status: Open
+Status: Feedback
Type: Bug
Package: Class/Object related
Operating System: Ubuntu 9.10
PHP Version: 5.2.13
New Comment:
Please use the same version of the dbg package than for php itself or
compile php in debug mode. The backtrace you provide uses 5.2.10 dbg
package.
We also need a small reproduce script.

I think this is a better backtrace - this is using the php5-dbg
package.
Program terminated with signal 11, Segmentation fault.
