Summary0001535: Laravel causes PHP warning (exception not caught) xdebug enabled, otherwise all is fine
Description

With xdebug enabled I can reproduce an error:

PHP Warning: Uncaught League\Flysystem\Plugin\PluginNotFoundException: Plugin not found for method: read in /tmp/laravel/vendor/league/flysystem/src/Plugin/PluggableTrait.php:49

without xdebug on, everything runs fine.

Steps To Reproduce

composer create-project laravel/laravel
cd laravel
composer require proengsoft/laravel-jsvalidation
php artisan vendor:publish --provider="Proengsoft\JsValidation\JsValidationServiceProvider" --tag=public --force

(I will try to make a smaller example)

Additional Information

Not reproducible with 7.1.8-2+ubuntu16.04.1+deb.sury.org+4
Reproducible after update to 7.1.18

bye the way ... the stack trace from the warning is enormous (not ending)

With php7.2 it works fine, maybe we just ignore the bug and switch to 7.2.3 :-)

without my setting

  • xdebug.collect_params=4

it works fine.

so I will be more careful with that in the future.

I think it is fine, that xdebug runs out of memory. A nicer error message would be cool,recommending to lower such settings.

The real bug is, that the exception is not caught properly while it is, when xdebug is on.

The real bug is is that Xdebug is reading variables that are already freed while constructing the exception stack traces. These variables are only read with xdebug.collect_params > 0. Reading already freed memory means all kinds of weird things can happen, and your errors are one of the symptoms, but I expect there to be many more.

If that's so, I suppose again that the PR for 0001665 ( https://github.com/xdebug/xdebug/pull/473 ) should fix this too?
