[MOAB-dev] memory leak

[Lukasz Kaczmarczyk]

Hello All,

I add entity (meshset) to another meshset. This generate memory leak according to valgrind. Pleas see attached log. 

Should I manage meshsets using childs and parents, or adding meshset to another meshest using  add_entities is accepted by moab.


Kind regards,
Lukasz
