.. and then anything can happen depending on what just happens to stand at that
memory location.

But this is a weakness of C when compared to
e.g. Basic, which issues an error when an index is out of the predefined range
thus
helping to debug the program.

I understand that checking the ranges might
slowdown the program, but IMO there should  be at least  the option for a
compiler switch
to generate a slow .exe which does this.
