Memory leak after 5.4.1->6.2.3 upgrade.

[Mateusz K. <mat...@an...>]

Hi !
We recently tried to upgrade from ancient PyCXX version we used (5.4.1) to 
newest 6.2.3 but we faced big memory leak after that change and forced to 
switch back to 5.4.1.
We have complex multithread C++/STL application running for hours, exposing 
it's calculation results via interface in Python.
What would be best way to find where is source of memory leak is?

Thanks in advance, regards,
