alt Hacker News> system C/C++ ABI
C++ abi should not be included in this. It is independent from the other pieces and historically a source of incompatibility on its own.
Saying "C/C++ abi" as if they are the same is looney tunes, the former is very simple and stable and the latter is very complex.

Somehow most of my portability issues seem to be caused by glibc, its symbol versioning and close ties to the dynamic loader. Minor versions aren't compatible, no two Linux distros ship the same version and you can't just provide your own without also patching in your own dynamic loader.
At least as far as the defaults on Linux go I consider C the root of all evil.

How libstdc++ initializes global variables absolutely depends on glibc and ld-linux.so. That is part of C++ ABI.
