"Memcache session handling, zend_mm_heap corrupted" on bugs.php.net

Sorry if you've already seen this. (The issue has no assignee or response comments on bugs.php.net, so I can't tell, and I personally don't check bugs.php.net frequently or know how to subscribe to bug reports for a given extension.)

• EDIT: https://bugs.php.net/search.php?cmd=display&package_name[]=memcache has an rss&rdf link in the html source code, so I guess a developer can subscribe

The bug was for memcache 3.0.9 with php 7.3. I can't reproduce the zend_mm_heap issue in 4.0.5.2 from PECL (trying with NTS on 7.4 only). However, I see a memory leak (same leak 4 times) instead in 4.0.5.2, when running with a PHP 7.4.3-dev NTS DEBUG build.
(The impact is hopefully limited to just a few http requests for sessions, and should get garbage collected after the HTTP response is sent? I haven't investigated further)

}
