Hi,

Is the solution multi-dll? This could be due to dll mismatch. I would ensure the whole solution is compiled together and the correct clarion / 3rd party DLLs are present.

Thanks,

Andy

It’s a ‘common’ error, it means you tried to access memory outside of what you should.  
In addition to what Andy suggested, try using the debug version of the rtl it’s in bin/debug off your clarion home directory. It gives a great deal more info that can be quite helpful in tracking the error.
