Hello, as per upstream ticket, there is a build failure (test failure) on ppc64
and ppc64el (confirmed on perotto and platti porter machines)
A simple fix is to make sure that O3 is not used on ppc64el (I don't care about
ppc64 because it has ~12 test failures
regardless of the optimization level used).
This is the patch I used in Ubuntu

Hi,
According to Gianfranco in [1] this is fixed since at least April 1 2025.
Marking it as such in the last Debian release before that here, too.
Best,
Markus
