Bug #79010 [Fbk->Opn]: __Call magic function is not invoked

Edit report at https://bugs.php.net/bug.php?id=79010&edit=1 ID: 79010 User updated by: stephen at sbillard dot org Reported by: stephen at sbillard dot org Summary: __Call magic function is not invoked -Status: Feedback +Status: Open Type: Bug Package: Reproducible crash Operating System: Windows PHP Version: 7.4.1 Block user comment: N Private report: N New Comment: I have Xdebug installed. It has not helped with the diagnostics. I have instrumented the code and from what that tells me the __call() function is never invoked. Instead things just seem to stop. I truly understand the problem of not being able to reproduce the problem. I've been there with my users. I can reliably reproduce the issue with a simple test case running on my full application. If there is any debugging options I should set I am quite willing to do so. I can also provide you with the complete environment and test script it you wish.

Do you have Xdebug installed? If not, try with it and see what happens. Also make sure you have your error reporting and logging settings set up properly for development and testing. ------------------------------------------------------------------------ [2019-12-21 00:26:17] stephen at sbillard dot org Description: ------------ The magic method __call() appears fault under some conditions. I am unable to create a simple script that reproduces the issue, though. I am making a method call on an object where the method does not exist. The object on which the method is invoked is a 4th level decedent from the object that contains the __call() definition. When the method is invoked all output to the browser is terminated. In fact, I can inspect parts of the page that are visible, but if I try to view the source (in Chrome) none is shown. I am using Wampserver 32 bit version 3.2.2.2. I can switch to PHP version 7.3.13 and the code works. To get the code to work on version 7.4.1 I have defined an __call() method in the first descendant object that simply invokes parent::_call(). I have attempted to create a simple test case with these levels of object inheritance, but that script does not fail. I regret that I cannot interpret the instructions for a gdb backtrace to the Wampserver environment. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79010&edit=1
