In Rust debug builds integer overflow triggers a panic.

Sticking to "modern C++" does not necessarily avoid safety issues. Sometimes it makes them worse. See https://github.com/isocpp/CppCoreGuidelines/issues/1038 for example.

It seems like a shame that arranging for behavior on overflow is so obscure in C and C++ programming circles, still. If C++ developers regularly arranged for known behavior and decided on policy for it, a whole class of bugs would be removed in that environment.

Certainly Rust having a sane default that is well-known is a significant improvement.
