This isn't always true.  Pointer aliasing rules become stricter but
still spec-legal with certain optimizer modules, for example.  I'd 99%
bet that mozilla or a dependency is to blame here.  However, that
doesn't mean that the port is non-functional.  It means that it has
known bugs in the non-default case that should be documented until they
are fixed.  I'm glad that Mikhail has exposed one of these problems, and
I hope that both a temporary and permanent solution can be found.
