| You can start with my demo mod (2 posts above). Maybe you can figure out what's wrong |

I don't really have a suitable environment to be testing this since I'm running visual studio 2012 and windows 8 64bit. Ingame nothing happens when the functions are called, server crashes when player deallocation takes place which will happen on any 64bit environment passing plugin-allocated memory back to nwserver AFAIK. Logfile doesnt indicate any errors either.

After some investigation, I probably managed to find correct malloc and free functions which should be used inside nwserver.exe. Should you need to allocate memory which will be later freed by nwserver (or deallocate memory allocated by nwserver), you have to use these functions, otherwise the application will most likely crash.
I am not 100% certain but these seem to be the correct ones: | Code: | void * (__cdecl *pmalloc)(size_t cb) = 0x00602657;
void (__cdecl *pfree)(void * cb) = 0x0060256E; |
I don't know where I can find names plugin so I cannot confirm whether this will help. If somebody has configured environment, where he or she can try it, I would be glad. I do not have NWNX2 for Windows installed so it would take me quite some time to test it.
Good thing is, this can be tested with any heap buffer (descriptions, names, variables, ...) so I think that if it is not already done, it has quite some advantages.
In other versions of nwserver.exe you can try to look for these signatures (if CRT remains the same): | Code: | free begins at: 55 8B EC 6A FF 68 00 6F
malloc begins at: FF 35 68 F8 EE 05 FF 74 |
Edit: I tested it with GetDescription and it seems that it does not leak and does not crash either. If somebody want to help with actual implementation, send me PM. |

Yes, there is a chance for that.
