How about we stop this discussion?  I don't think anyone was 
volunteering to implement a solution anyway.  To sum up the 
alternatives:  you repeated the argument for one side above.  Other 
people want their program to do the same thing whether bounds checking 
is enabled or not -- except in the case where the non bounds-checking 
program would have made an out-of-bounds access.  Neither party is 
"right", I consider this latter behavior preferable.

Thank you, and goodbye.
