Hi, I've encountered a problem in asCMemoryMgr while using AngleScript in different threads. In one thread I run asCScriptEngine::ExecuteString() while an other thread calls asCScriptEngine::GetTypeIDByDecl(). The latter thread sometimes causes a segmentation fault in asCMemoryMgr::FreeScriptNode(), because asCScriptEngine::ExecuteString() calls asCMemoryMgr::FreeUnusedMemory(). This leads to simultanous access to the scriptNodePool member. I added a critical section in every asCMemoryMgr method that accesses scriptNodePool. That seems to fix the problem. If you'd like to have the changes i can mail them to you. Regards, Tim

Yes, please send the changes to me.

Multithreading is always difficult to test, so any help in this area is always welcome.

Regards,
Andreas
