Posted the Valgrind HEAP Summary showing the memory allocation in the shared library … When the pointer goes out of scope, that memory must not be deallocated. Bug?

Is this pointer a std::unique_ptr? How does one deallocate said pointer after it goes out of scope? Valgrind identifies a definite memory loss in libRDKitChemReactions.so from a new(unsigned long) Thanks, J Sent from my iPhone _______________________________________________ Rdkit-discuss mailing list Rdkit-discuss@lists.sourceforge.net https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.sourceforge.net%2Flists%2Flistinfo%2Frdkit-discuss&data=05%7C01%7C%7C8d25b02bc4ab44cc1ad708db7beda725%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C638240032871322956%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=8Dmfydb9VO9ApXMonLqqRQot3LUvpD4ijtWUmOrUPWw%3D&reserved=0
