For code:
for (unsigned int k = 0; k < BS; k++)
{
s += A[k] * B[k];
}
PR48052 handles this, and for this code, the additional runtime check seems not
required.
If there is offset in code:

Since there are additional costs for the run-time check, we can see the benefit
if upbound `m` is large; if upbound is small (e.g. < 12), the vectorized code
(from clang) is worse than un-vectorized binary.

Somewhat more reduced:
struct X { constexpr X(int&) {} };
template struct Y {};
int a;
auto h(int b) -> Y; // #1
auto h(int b) -> Y; // #2
GCC accepts #1, but for #2 it produces seven (!) error messages:

thanks FX..
That single patch is definitely "necessary, but not sufficient".
