[NOTE]
You may have encountered a bug in the Ruby interpreter or extension libraries.
Bug reports are welcome.
For details: http://www.ruby-lang.org/bugreport.html


This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

I'll bet this is because I changed the prototype for the ClearEventLog function. If you pass an empty string I'll bet it works.
