Oh, neat, I just tripped over this bug myself.  (Can't review your
patch though, sorry.)

A related question: I was looking into GAS support for hppa64-hpux11
style COMDAT groups when I hit the bug.  The trouble with this is, it
seems to require multiple sections with the same name.  I have no idea
whether BFD can do that.  Does anyone know?  (This may not actually be
a requirement.  It is poorly documented and I am having to reverse
engineer aCC output.)
