More reliable is to have non-virtual destructors be, say,
protected instead of public when possible. The language rules
then lead to issues that all the C++ compilers should report
violations of if a delete via a base-class pointer is
attempted in the source code.

I quoted a bit on the subject from the "C++ Coding Standards" book in:
