 New Comment:

Thanks for the valgrind report, but unfortunately this is useless.
The warnings at the top are bogus, and everything after the SIGINT
is irrelevant.  Sorry for requesting it!

I wouldn't know how to proceed with this issue.

I can't reproduce this either.

In addition, I see no possible path to a leak.

I create a clean VM on Digitalocean, and reproduced it, this is the video and valgrind test result:

For me there is no difference whether ther is $wr->get(),
!$wr->get(), or neither; memory consumption increases until GC
kicks in.

Are there any leaks reported when you're running under valgrind
(set USE_ZEND_ALLOC=0)?

emmm, I reproduced it with a clean container, this is the video:
