Hi,

I see there have been a lot of updates & fixes to elftoolchain since
the last import into FreeBSD/head nearly 8 months ago.  Are there any
plans to update the import?

I'm asking because it appears that ctfconvert currently crashes
(specifically, due to a bug in dwarf_attrval_unsigned()), if you try
to use it on C++ object files.

This is easily demonstrated by applying this patch to FreeBSD/head and
building sbin/devd with WITH_CTF=1:
http://people.freebsd.org/~will/add-ctfconvert-to-cpp-object-files.diff

Justin Gibbs (cc'd) posted about this issue in February, and it's
still a problem:

Thanks,
--Will.
