"into" does not give much indeed. But ssa should point you to
pass_build_ssa and pass_del_ssa, which should reveal a lot.

It is a pedantic warning. Pedantic warnings are warnings in C and
errors in C++, unless you use -fpermissive.
So if you are seeing this in C++, the change was intentional because
PR24924 was fixed. If you are seeing it in C and you are not using
pedantic-errors, then it is probably a bug.

I think it would be worth mentioning this on
