--- Comment #6 from David Oliver <david at rgmadvisors dot com> 2011-11-08 21:55:46 UTC --- Created attachment 25760 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25760 8 Tests plus 1. I've added test 9 to Ben's set which is a likely usage of the feature, e.g. automatically converting std::string to a C string for printf(). Unsurprisingly, this case also fails on 4.6.2. Cheers! David.
