Ah, I read "C11."

Yes, you are correct, but I don't think there's an ABI issue. An ABI issue is much harder to deal with than a semantic change.

With an ABI issue you've got to recompile the world (your project, libraries it links to, etc.) to get a working application. With a semantic change you only recompile the bits that had to recoded to account for the change.

YMMV, as usual.

We recompile the world anyway, so ABI change is less of a problem, but the fact that just a recompilation does not fix the issue and you need to do a lot of investigations is a problem.
