many ERROR : LEAK 8 direct bytes - INVALID HEAP ARGUMENT

[Juaneme]

OS = Windows10 - Visual Studio 2010

I got a lot of ERROR : LEAK 8 direct bytes - INVALID HEAP ARGUMENT for example :

When I call : 

ifstream config_file(name, ios::binary);

Error #32: LEAK 8 direct bytes 0x0000000004489390-0x0000000004489398 + 0 indirect bytes

 Are these errors known errors ?

How can I hide these errors ?
