| Summary | 0001151: Crash when another extension calls call_user_function() during RINIT | ||||
| Description | (PHP 5.6.4) When trying to use xdebug and the phk PECL extension, php during first RINIT without executing anything.

If I remove this call, everything works fine. Problem because I don't know another way to register an autoloader from an extension. | ||||
| Steps To Reproduce | Download the 'phk' PECL extension (clone it from github:flaupretre/pecl-phk, don't get it from PECL). In the 'develop' branch, look for the 'xdebug_2.3.2_crash' tag. This is the version I experienced the problem with. Compile and install. Activate in php.ini along with xdebug. Run the 'php' CLI command. | ||||
| Tags | No tags attached. | ||||
| Operating System | |||||
| PHP Version | 5.6.0-5.6.4 | ||||
|
|
No need to clone a specific version. The phk package released on PECL (3.0.0) shows the same problem. |
