After upgrading to angelscript 2.31.1 from angelscript 2.30.0 the following block of code will cause a runtime assert failure when compiling

bool Init() {
    const bool show_invisible = false;
    if(show_invisible == false) {
        Print("Hello");
    }
}

Removing const from the bool makes the problem disappear. Evaluating if the bool is true does not cause a problem however. Following is a stack trace from the crash.

This happens on an amd64 linux platform. Example is from placing the block of code in an otherwise empty script file

Thanks. This looks to be similar to the problem fixed in revision 2349, but at a different location in the code.

I'll have it fixed too.

Cool, glad i could be of service.

I've now fixed this problem in revision 2354.

Regards,

Andreas
