Crash reduced to 13 lines of code

Somebody who knows how to debug FXRuby please help…  The following 13 lines of code will cause a seg fault immediately on Solaris/Ubuntu.  I can’t make it any simpler than this.   The code dies in the garbage collect mark code trying to get the focus window from FXApp (apparently because memory has become corrupted).

Thanks,

Ryan

application = FXApp.new("NA", "NA")

FXMessageBox.warning(FXApp.instance, MBOX_OK, 'Warning!', 'Are you sure?')
