Unfortunately, I have not yet been able to reproduce this.

The unit tests seem to work fine on my Fedora system with gcc-10.2.1,
so this might be related to some other change at the time?

I remember cmocka being a bit fragile from the time the unit tests where
added. The "--enable-unit-tests" configure option tries to manipulate the
CFLAGS from within the configure script to make it work. Is your build
system perhaps attempting to set the CFLAGS externally at make time?
