Looks similar to #165

I cannot reproduce this on Intel processor, but it looks like issue #165, which can be resolved passing -fno-strict-aliasing when compiling. The issue would only be in reference code in the tests, so it would be a minor issue anyway. I'm closing this issue, feel free to reopen if the workaround does not help.
