--- Comment #2 from Jason Merrill <jason at gcc dot gnu.org> 2011-03-08 15:14:02 UTC --- Created attachment 23583 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23583 Fix Here's a patch that fixes the bug and passes regression testing. I don't plan to put it in for 4.6.0 as I'm concerned about possible side-effects; I seem to remember trying to do exactly this once before and it causing problems. I'll put it in for 4.7 once 4.6 branches, and then perhaps into 4.6.1.
