I use unity3d in order to make a visualization for a computer experiement, which is written in C++. So i wrapped it into dll file and tried it. Some functions worked fine, some did not. The probable issue might be the following: i allocate memory for an array of doubles in c# code, then pass the pointer to c++ dll function and then try to read from it. Can't see anything wrong with it, but if i erase the part of the code responsible for that, it does not crash.
