This is with the PHP 7.3.1 provided by MAMP on Mac OS.

[oliverklee]

I get the same result with the MAMP PHP 7.2.14 and 7.3.3.

[oliverklee]

This is how manuall run what is tested by the end-to-end test:

./phpunit --no-configuration --bootstrap tests/end-to-end/regression/GitHub/2591/bootstrapNoBootstrap.php tests/end-to-end/regression/GitHub/2591/SeparateFunctionNoPreserveTest.php

This is supposed to fail with 2 errors.

[oliverklee]

Educated guess as of the history of #2591: This might be causes by certain settings in my php.ini.

[sebastianbergmann]

If that is the case then we may need to pass (more) INI settings to the child process. This was recently done in #3506.

[oliverklee]

This is the php.ini for PHP 7.3.3 on my system where the problem occurs:
php7.3.3.ini

The tests now work fine for me with the latest PHPUnit master, 8.3 and 7.5 and the latest MAMP. So this issue can be closed.
