--- Comment #21 from Jonathan Wakely <redi at gcc dot gnu.org> --- std::vector should be preferred in C++. This warning will not drive responsible C++ developers to use alloca, it will drive them to use std::vector. As Aaron has said, there are cases where people use a VLA in C++ by mistake without even realising it, just because the code compiles and they don't notice they're using a non-constant bound.
