I'm pretty sure GCC has been ABI stable far longer that MSVC which used to break ABI every release.
GCC was forced to break the std::string ABI by the C++11 standard and they have been lobbing ever since against ABI breaks.
- pjmlp 4mo agoYou haven't used Windows in a while I imagine. MSVC has stabilised the ABI since VS 2015, we are on VS 2026 now. Due to customer pressure to stop doing exactly that, to the point some ISO C and C++ stuff that requires breaking the ABI has not been implemented thus far. I am quite certain that I will find ABI breaks in GCC release notes since Slackware 2.0, when I used it for the first time.
