--- Comment #5 from William J. Schmidt <wschmidt at gcc dot gnu.org> 2012-08-13 14:24:48 UTC --- Well, I'm embarrassed. The tests I wrote for this functionality never got into the test suite -- I apparently forgot to submit them with the patch -- and I can't find them anymore. I'll write some new ones soon. Apologies for the oversight. :(
