please forwarded these upstream, mudflap doesn't see much attention.

Apparently, they're already forwarded. It's just that nobody's doing
anything about them. The mudflap code, as implemented, is incorrect.
It's not just incorrect on GNU/Linux, it's incorrect on FreeBSD, NetBSD,
OpenBSD, Solaris, HP-UX, OSF1, Mac OS X, and according to POSIX. In
fact, I could not find a Unix that provides dlopen(3) but does not
permit NULL as a valid value for path.

There's even a patch that I provided, which is trivially correct. I'm
just trying to find out if there's a reason why this bug hasn't been
fixed after three years.

lack of interest? I'll apply a tested patch for 4.4/4.5, if you send one, else it might be better to tag the report as wontfix.
