Some issues with the determination of the speed, caused somewhat memoryleak, causing the program to crash and end up in either dummy handler, or application stack overflow hook function.
I have cut down on some of the largest buffers as these had been designed too large for debugging purposes. However, the speed determination algorithm has now been redesigned, and the problem seems to be solved.
