[Bug 2027598] [NEW] IM-6 causes memory leaks when used with PHP after upgrade

[Piotr P]

Public bug reported:

After upgrading ImageMagick from 8:6.9.10.23+dfsg-2.1ubuntu11.7 to
8:6.9.10.23+dfsg-2.1ubuntu11.9, our PHP server that renders images
started using up a lot of memory. Some changes in IM6 (or some bad
incompatible implementation in php7.4-imagick plugin) is causing
apparently memory leaks.

This was reproducible both on AWS EC2 instance and inside 20.04 Docker
image.
