Meh, wrong patch, sorry. I must have had traces of my other approach
still in dwarf2read.c that this worked when I checked before sending. It
actually fixes only the partial DIEs and I'm not even sure if that's
necessary. It certainly does not fix the problem for reading full DIEs.
As it's a rather generic tree reader (read_die_and_children_1 and friends)
it seems a bit clumsy to special case bogus namespace dies there, which
brings me back to my other option (that's the one I started and tested
with), hacking determine_prefix, like below. That fixes the problem.
Really :-)
Ciao,
Michael.
