  struct V : _V_base {

The patch that Janis identified in comment #5 fixed bug 19497, which is only an
"accepts-invalid".  Bug 19497 was not fixed on the GCC 4.0 branch.  Perhaps
that patch to fix it for GCC 4.1 should just be reverted if a fix for this bug
here can't be found quickly.

simplest test case

This appears to be tickling a latent bug in the dwarf code.  Before my patch I
discover that the structure's dwarf information appears to be a child of
comp_unit, whereas afterwards it's a child of a namespace.  the latter seems
correct to me -- I am investigating.
