Subject: [PATCH] Fix tests: Prevent stack overflow during dtor

On s390x the stack is smaller and/or the object dtor code uses more stack,
which causes the destruction of deeply nested objects to crash in these
tests. Here I ensure that objects are released one by one at the end of the
tests to avoid recursive dtor.

Closes GH-16561
Fixes GH-16528
