Answer 1

This is a valuable comment by @Evgeny Sergeev that I promote to the answer:

For GCC, you can -D_GLIBCXX_DEBUG to replace standard containers with safe implementations. More recently, this now also seems to work with std::array. More info here: gcc.gnu.org/onlinedocs/libstdc++/manual/debug_mode.html

I would add, it is also possible to bundle individual "safe" versions of vector and other utility classes by using gnu_debug:: namespace prefix rather than std::.

In other words, do not re-invent the wheel, array checks are available at least with GCC.
