Updating to 1.0.4 on Fedora Rawhide I'm seeing:

Thanks @opoplawski I'll leave @alaingdl check this, I was wondering if #1655 was closed?

[alaingdl]

Since it is a problem only on ppc64le I have no way to test further.
This test is OK on M1, M2 (arch & OSX) & x86 (u & deb)

I also tried changing the type of noise (--no-dSFMT), no change ...
