It is just a impression because I've never heard about such a strategy to
ensure correctness. I only know, in debug mode msvc-stl-code is several
times slower than in release mode, due to disabling optimizations and
executing additional checks.
But a proof would only be a aspell benchmark which I don't have.

Yes, I also think a crash is better than to silently ignore it.
