Stefan, let me thank you for what seems to me to be the correct
concept.
I searched this whole thread in google for setjmp and YOU are the only
one who mentioned it. I applaud you. Because, it does not seem that
there
is any other construct that can implement try-catch-throw. I still
have to
read up on it, but thats what my gut instinct says.

Anyone, care to show how this translates into assembly after we deal
thoroughly with this in the context of C ?

Everyone, please ignore the the mean spirits trying to derail a
serious
conceptual discussions and calling each other trolls or giving
obfuscated
explanations for ego purposes, and not LUCID explanation.
