From the tutorial: handle<> main_module(borrowed( PyImport_AddModule("__main__") ));

i write these codes just now:
class xx
{
protected:
handle<> m_Module;
}

then it causes leak already.

How are you detecting your memory leaks ?

using mfc method, overload new opreator,
and also using boundchecker.

my codes:
void Initialize( void )
{
if (!Py_IsInitialized())
{
Py_Initialize();
}

handle<> main_module(borrowed( PyImport_AddModule("__main__") ));
}

only these codes, and i dont excute this function, it also causes leak!
i cant understand. faint....

If you don''t call the function, then your problem obviously lies elsewhere.

As much as i''d like to bash Python i have to say, that Boundschecker sometimes doesn''t recognize globals/non-pointer-members as being automatically removed/deleted. Boundschecker is a fantastic tools for finding leaks (and more) but sometimes it doesn''t show things right.

Try to add that handler as a pointer, new it on begin and delete in on the end. If the memory leak is still there then it''s real.

If the leak points to inside the boost.python.something then you could look into the boost.python FAQ or email the boost.python guys.
