--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-01-18 13:00:26 UTC --- Oops, the g++ diagnostics I showed were from 4.4 not 4.6, but they're the same except 4.6 adds column numbers I've created PR 47343 for the incorrect line number in the case where the partial specialization is declared but incomplete.
