No, it's just that gdb can't debug things with -feliminate-dwarf2-dups
on yet.
I basically had to rewrite large portions of the dwarf2 reader because it makes
stupid assumptions (though i can't fault this, because it's based on
the dwarf1 reader, where these assumptions are valid), and I don't
want the hassle of trying to get the  patch approved, because it
basically, well, rewrites the dwarf2 reader, making it a pain in the
ass to get approved.
If someone else wants to herd it through the gdb patch approval
process, i'll happily send it along.
