Due to the changes in the rest of the patch, erase is called with pos == size(), but with tracking off it doesn't do anything. ... > > In general, I'd prefer to see smaller patches, especially if they are > > going to land in 1.4.

Now I am personally confident, having added and verified the hasSameLayout mod. Third party testing is never a luxury though. - Martin
