I've just spent a weird two days finding out a bug. It occurs that some 50 percent of our testers couldn't get the program to start, it had a so called mysterious crash on startup. I was able to pinpoint the location of the crash to RegisterScriptString. Weird thing is, that it wasn't giving any errors to the program, it just crashed. The lesson here is that I was using a scriptstring implementation from last summer with the new AngelScript version, and changing to a newer one fixed the crash. Obviously I hadn't remembered to update it lately. I was just thinking that is there a good reason to keep scriptstring separate from the library?
