Thanks a lot for your investigation!

I know almost nothing about hppa, and I don’t have much time to debug this,
but if you provide a patch that will make more tests pass on hppa (and does
not break other architectures), I will be happy to apply it (and help with
pushing it upstream).

Quick search showed me #810859 which looks like a similar problem in a
different package.
