But even then, if 4.3.x is supposed to be maintained, it's a bug since
the behaviour doesn't match the documentation. The documentation
claims inlining even with optimization turned off being the primary
purpose of the `always_inline' attribute.
What about the new register allocator, does it work for the AVR?
AFAIR it ought to be the default starting with 4.4.x, did that happen?

Never trust an operating system you don't have sources for. ;-)
