run-time errors

["Andrei A. Voropaev" <avorop@...>]

Hello!

I'm trying to understand handling of run-time errors by lua. Can you
please give some examples of those errors (division by zero leads to NaN
:)

What does it mean that in lua_call "any error inside the called function
is propagated upwards (with a longjmp)"? Long jump to where?

Thank you

Andrei
