The issue is that the self-test fails for 16 out of 30 times, i.e. it is kind 
of random when it happens or not.

I am unable to reproduce it with i386 and clang-13. I can also not reproduce 
it with GCC.

Nor do I see an obvious issue in the code that points to either uninitizlized 
memory or otherwise could affect the test result.

I keep trying with Clang-14


Ciao
Stephan
