gas has a bug that produces an incorrect prologue_length for 64-bit DWARF.  As it turns out we can handle that condition, so we can still return true.

I fixed the underlying bug in FreeBSD here:
http://svnweb.freebsd.org/base?view=revision&revision=256692
and your note reminded me that I never forwarded this to the binutils upstream, so I've now posted to their mailing list as well.

Maybe just drop the message?
