Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID --- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-04-13 09:52:03 UTC --- Yes, this is invalid. If you want to do this then you need to call reserve on the vector so that push_back doesn't cause reallocation (or decide if the code shouldn't just be rewritten differently!)
