Description:
------------
Memory bugs such as leaks and access to freed memory are detected by phpt tests in debug mode. This happens in git PHP-7.3 and in git master (8.0). I guess, the same is for 7.4. This may be replicated:

- access to freed memory: when using LDAP_CONTROL_VALUESRETURNFILTER
- memory leak: when using LDAP_CONTROL_PRE_READ, LDAP_CONTROL_POST_READ, LDAP_CONTROL_SORTREQUEST, or ldap_exop_passwd() with 5 arguments.

I believe, this bug is now fixed via php-src PRs: #5764, #5799, #5801, #546, #5851.

Mistake. Should be #5794, not #5764.

.. and #5846 instead of #546. So the correct list is  #5794, #5799, #5801, #5846, #5851.
