Rust is particularly sweet to work with in that regard.
Running unit tests with the address sanitizer and UB sanitizer enabled go a long way towards addressing most memory safety bugs. The kind of C++ you write then is a far cry from what the haters complain about with bad old VC6 era C++.

Here's a long list of C++ unit testing frameworks: https://en.wikipedia.org/wiki/List_of_unit_testing_framework...
