I was able to reproduce the problem under qemu, and it is unclear to me whether the problem is actually a missing step in dense-to-sparse conversion, or simply a problematic assert after. It seems to be an issue showing up only on this architecture, because the numerical results of the test are slightly different, but this is possibly revealing a logical error in how dense to sparse is working or how the results are checked. Therefore, I have reported it upstream [0] and will try to include a patch in a package update if/when we are able to determine what is going on here.
