Symfony version(s) affected: 4.3.3 (this does not happen in 4.3.2)
Description
Freshly updated to 4.3.3 and my tests started crashing with notice Undefined variable: active.
Turns out the issue is in this line which was added recently.
If I declare $active=NULL; before passing it to curl_multi_exec(), the notice goes away.
Now, even PHP documentation uses a code example where the $active variable is undefined when passed into the function. Based on some more reading I believe that PHP should not raise a notice when an undefined variable is being passed into a function as a reference, but that is for some reason happening to me.
How to reproduce
- Set up PHPUnit with
convertNoticesToExceptions = "true" - Run PHPUnit
KernelTestCase, execute a request and invokeKernelTestCase::ensureKernelShutdown().
Possible Solution
Initialize the $active variable before passing in to a function.
