> I wonder if we can add -fmax-type-align=8 for extension types...

No, we cannot: it's a temporary fix. The flag causes compilation error if it's added to old version of clang or to a C compiler different than clang.

> Any ideas about reduce impact for Python 3.7?

I don't think that it's a matter of performance here. What matters the most here is correctness.

See Florian Weimer's message:

"This issue potentially affects all compilers, not just Clang."
