Why bother. All thats needed is a new keyword, perhaps "safe".
Trivial example:
safe
{
int i[10];
int j = 10;
cout << i[j];
};
This would fail to compile or if the check couldn't be done at compile time
any invalid memory accesses within the "safe" block could runtime abort with a
useful error instead of just ploughing ahead and crashing or corrupting the
code later anyway with the expense of runtime checking costs.
Possibly even a handler function could be set for this eventuality (no,
catching a SIGSEGV/BUS isn't the same as you don't know whats been corrupted
so can't do anything useful in the sig handler anyway).
