Yes.  If I remember correctly, casting a pointer to an integer type
is implementation defined.

This definitely needs a PR.  It should be marked as a regression.
This probably also breaks the unwind code in libjava as it has a
similar check.  There's also __canonicalize_funcptr_for_compare.

It's something of a puzzle as to why this didn't appear in testing.
It suggests we aren't testing the build libraries but installed libraries.
