Randomly failing tests on MacOS

[Isty001]

Taking a look at the actions results it seems some tests fail on Mac, but not always.

Running clib(1) tests

Edit: I can't reproduce any of it on Linux now.

This log file might give some hints. It's from when I built with gcc 11.1.0 on Debian Bullseye and added the -fanalyzer flag.

I had some problems recently with tests randomly failing on MacOS using Travis CI. Turned out to be a cache issue.

Btw, I've found Coverity to be a useful tool for testing. Although it sometimes gives false positives, it's pretty good at spotting potential resource leaks or buffer overflows.
