Why doesn't the compiler detect out-of-bounds in string constant initialization?

Question

I read this question and its answer in a book. But I didn\'t understand the book\'s justification.

Will the following code compile?

Answer 1

Array-bound checking happens at runtime, not compile time. The compiler has no way of doing the static analysis of the above code that would be necessary to prevent the error.

UPDATE: Apparently the above statement is true for some compilers and not others. If your book says it will compile, it must be referring to a compiler that doesn't do the checking.
