looking for fuzz failure

These tests were isolated from their respective minimized test cases.

The tests work fine and pass path ops internal validation;
hopefully some more intensive x-san or valgrind test will help
isolate the bug.

Sheriff, please revert if it fails and I don't get to it first.
