Thread: MS STL strikes again

I've been working on resource management again and found a problem related to debug new and std::map.

This code:

Code:

_Nodeptr _Buynode(_Nodeptr _Larg, _Nodeptr _Parg,
  _Nodeptr _Rarg, const value_type& _Val, char _Carg)
  {	// allocate a node with pointers, value, and color
    _Nodeptr _Wherenode = this->_Alnod.allocate(1);
    _TRY_BEGIN
    new (_Wherenode) _Node(_Larg, _Parg, _Rarg, _Val, _Carg);
    _CATCH_ALL
    this->_Alnod.deallocate(_Wherenode, 1);
    _RERAISE;
    _CATCH_END
return (_Wherenode);
}

Fails on the bolded line if you define new as debug new prior to including std::map. The placement form of new works fine with the normal new but fails on the debug new that tracks allocations and de-allocations.

Nice eh.

The sample for std::map in the help docs for MSVS will not compile if you are defining debug new prior to using std::map.
