Fio is in fact newer than mine. Mine is 3.39.

Others are mostly the same version.


And indeed it's bash, after rolling back to v5.2.037 bash, everything is 
fine.

It looks like it's bash 5.3.x starting to fail (5.3.0 tested and failed).

I'll try dig a little deeper, and this is why I'm always running 
Archlinux (ArchlinuxARM in this case), to give some early warnings of 
some unexpected updates breaking the test cases.

Thanks,
