<p>The function <b>osRtxErrorNotify</b> must contain an infinite loop to prevent further program execution. You can use an emulator to step over the infinite loop and trace into the code introducing a runtime error. For the overflow errors this means you need to increase the size of the object causing an overflow.</p>
