| Description | I have a problem using Xdebug with PHP-GTK 2.0.x
If I create a class that extends GtkWindow, and then try to create a new GtkComboBox anywhere in that class, I get a segmentation fault.
In classes that do not extend GtkWindow, I get no such error. If I remove Xdebug from php.ini, I don't get the error either. |

$objTest = new MyClass();
echo "Finished\n";
