Not just C++; even C has this problem to a small degree. The ELF ABIs don't cover the full C language; if I change a significant preprocessor definition, or a const that my library never takes the address of, the resulting .so will not change, and yet I can change my ABI by doing so.

We just ignore this for C, since distros do the work of making sure that C developers don't destabilize their own ABIs this way, but it's still an issue, even in C.
