Yes, and it works, but it fails when running in multi thread mode. Anyway, I
am able to reproduce the problem here.

That is interesting, Float precision might be a platform characterstic,
mainly if using long double, or, quad float precision.
Anyway, I will go deeper in the code to understand the problem here.
I might eventually just bypass testing for ppc64el to let the package
transition to testing, unless you think you are gonna have a fix ready
very soon. With the transition window extended to 10 days and the
soft-freeze deadline happening, I cannot wait for very much longer.
Please keep me up-to-date, and thanks for investigating.
