I'm using Windows 8.1
Windows build rtmpdump-2.4-git-010913-windows.zip download from https://rtmpdump.mplayerhq.hu
Just FYI, thank you for your help, I downloaded a new version (I believe) and it worked nicely. Thank again, Anastasios Andronidis

This is clearly a diagnostic catch for an unallocated memory access bug in rtmpdump. So, it's a real bug - possibly a serious one. But it will only be picked up by libraries that are capable of detecting such bugs. Because most memory management libraries do less checks than yours, you're in the privileged position of seeing the crash :) Congratulations! Unfortunately, finding such a bug is pretty difficult and/or requires the use of run time debugging tools.
