Access violation when accessing string

[yiochen]

I tried to run Demostration4.cpp where you read in a file and try to access a string defined in the lua file. Visual Studio 2015 reports Access Violation on that. This is the call stack

Anyone knows how to solve it?

Nevermind. I found out why. The problem was that Visual studio doesn't know where to look for the config.lua file. So the code failed to read the file. Moving config.lua to the root directory of the LuaCppTest project solved the problem for me. I am sorry.
