[nashif]

@cfriedt bisection leads to 0ac931b, any idea what is going on here?

[cfriedt]

Yes. I'll submit a PR

[cfriedt]

@nashif - is there a way to automatically run this test suite when there are changes under lib/posix?

[cfriedt]

Found a better way than what is in #85327 currently. Will re-use that PR to fix the regression.
