Memory Leak Test Failure

[rossimo]

I haven't been able to replicate this again, a subsequent re-test passed.

What flags were set during compiling?

[rossimo]

It was a simple "make", I didn't add any flags.

I'm guessing this has been resolved already. It's both old and also doesn't turn up in the CI. We've also since fixed some possibly related issues: #8213, #7757.
