This is a massive improvement to stability and safety when using the plugin, as all exceptions should now no longer be leaked into C controlled code, which can't actually handle exceptions at all. Warnings fixed: * Potentially throwing exception during library load. * Possibly throwing function passed to C. * Statement does nothing. * Variable is initialized but not referenced. * Variable overloads variable in parent scope.
