From: Vladimir Grigoriev on 15 Dec 2009 10:27 I am sorry. The original code is not complete because I did not know what part of my code generates the error. I have shown the complete problem code. I am using VC 2005 C++ EE. Vladimir Grigoriev "Leigh Johnston" <leigh(a)i42.co.uk> wrote in message news:%23pnIkpZfKHA.2184(a)TK2MSFTNGP04.phx.gbl... > Looks ok and compiles fine for me on VC9. >
From: Vladimir Grigoriev on 15 Dec 2009 10:45 It seems like the vector uses my template minus operator. I think that it is a bug of VC++. Vladimir Grigoriev

The code is fine. Consider upgrading your compiler, maybe? V -- Please remove capital 'A's when replying by e-mail I do not respond to top-posted replies, please don't ask

Why do you want to do that? Bo Persson

The code must be compiled because it has no any invalid code. It is bug of the Microsoft realization of vecotrs. The error occurs in the followin function frim <vector> iterator insert(iterator _Where, const _Ty& _Val) { // insert _Val at _Where size_type _Off = size() == 0 ? 0 : _Where - begin(); _Insert_n(_Where, (size_type)1, _Val); return (begin() + _Off); } It seems that for the statement size_type _Off = size() == 0 ? 0 : _Where - begin(); my template minus operator is used. Instead of a size_t value _Where - begin(); generates const inerator.
