I am using OCE 0.9.1 binaries for MSVC 2010 SP1 for my cad program. I have a function that gets run from 4 different threads in parallel. This function uses BRepAlgoAPI_Fuse & BRepAlgoAPI_Cut that cause data race (or not). I have a few questions:

1. Do I have to recompile the libraries with set MMGT_OPT=0 option?
2. Where do I use Standard::SetReentrant(true)?

Just any tips how this is done will help. ty

Although we are working on it. You are also welcome to develop
