Hi Andreas,

I already noticed.

I don't have a better idea for that than sending you a MR to disable 
this test on i386.

Ubuntu has problems with a different test in this package on ppc64el 
where they are building with -O3,[1] so this package seems to have
fragile tests.

This might end up being similar, but there is some weirdness going on here.
I'll let you know if patching is needed.
