When I wanted to open one of my own chessbase databases, scidb crashed. I figured out that it must be something with the eco codes, and when I changed the code for convertEco function in cbh_codec.cpp it was fixed and I could open the database again. Attached to this message you can find the patch and the source database causing problem.
