--- Comment #4 from Zack Weinberg <zackw at panix dot com> 2013-02-01 00:48:43 UTC --- Is vstring going to be promoted to std::string in the *near* future? it doesn't seem done to me, eg there is no stringstream for it, and it appears to generate bulkier code. (not scientifically benchmarked) that said, it doesn't fail this test case, but I haven't checked how its clear() works, so I'm not sure it has no bug here.
