New submission from Филипп Пономарев:

I've created Win32 app (MFC+ATL)
Added includes, added \python35_d.lib

runed main.cpp:
int main()
{
int nRetCode = 0;

HMODULE hModule = ::GetModuleHandle(nullptr);

if (hModule != nullptr)
{
// initialize MFC and print and error on failure
if (!AfxWinInit(hModule, nullptr, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
wprintf(L"Fatal Error: MFC initialization failed\n");
nRetCode = 1;
}
else
{
Py_Initialize();
Py_Finalize();
return 0;
}
}
else
{
// TODO: change error code to suit your needs
wprintf(L"Fatal Error: GetModuleHandle failed\n");
nRetCode = 1;
}

return nRetCode;
}

[issue27734] Memory leaks at Python35-32

Филипп Пономарев added the comment:

Hmm. Correct me if I'm not right.
You agree that you have leaks, but you will not do anything with them until 
they start repeat in a loop? So I've updated problem.

Thnx about nosy, idk.

What I want is to use Python API without leaks in my programm.

The problem is here:
1. I've created test.dll, which is static linked with Python. I've function 
tstf there:
void tstf()
{
Py_Initialize();
Py_Finalize();
}
(ofcourse I've imported it in source.def - tstf @1)

And I have main dll:

typedef void(*vv)();
void exec()
{
HMODULE hModule = ::LoadLibrary(L"d:\\PATH_TO_TEST.dll");
vv fnc = (vv)::GetProcAddress(hModule, "tstf");
(*fnc)();
::FreeLibrary(hModule);
}

int main
{
exec();
//exec();
//exec();
}

So I get more leaks because of more call exec() function.

Waiting for your answer, than you!
