--- Comment #7 from Richard Henderson <rth at gcc dot gnu.org> 2011-03-08 22:27:31 UTC --- The name isn't being properly demangled. Although this ought not matter for correctness; what matters is that the group name is consistent across all uses, and that functions that are not related are not grouped together. I'll still see about fixing the demangler such that the group name is handled. Can you please point me at the full test, so that I can see the linker errors?
