--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-07-28 14:45:11 UTC ---
So, how are the group signature symbols supposed to be emitted on
SPARC/Solaris?  A dummy symbol of that name somewhere in the section?  Can it
be local, or must it be global symbol?
Would something like:

       ref->info = NULL;
fix it?  Of course I'd prefer if this was limited to targets where the
assembler isn't capable of handling it correctly...
