This is most likely the same issue we found in https://bugs.freebsd.org/216770, which was reported upstream to LLVM here: https://bugs.llvm.org//show_bug.cgi?id=31928, and resulted in a very long and not really productive discussion about whether type punning in this way is officially allowed, or a GNU extension. I will gladly leave it to language lawyers. :) In our case, easy fix was to use -fno-strict-aliasing, as we did here: https://svnweb.freebsd.org/changeset/base/313706
