It's possible that it is compiler settings, try to turn off all optimizations, and see if the problem goes away.


Try commenting out code from your application and script so that as little as possible remains that still reproduces the problem.


If you can come up with a single line script that reproduces the problem, then you can set a break point in as_callfunc_x86.cpp : CallSystemFunction. You ought to be able to determine what may be going wrong then.

Interestingly, the MinGW Release target in the Code::Blocks project had no optimizations turned on, and other than that, I was testing it in a Debug build for my code.

I'm going to begin with creating a one line script and doing what you said.
