Interesting idea. But it is better than the explicit undefining of malloc macro? The advantage of pragma solution is that it contains explicit "#if defined(_DEBUG) && defined(_CRTDBG_MAP_ALLOC)" guard which describe why it is needed. Parenthesis solution around malloc does not explicitly describe why and when it is needed. _______________________________________________ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
