Follow-up Comment #2, bug #41435 (project avr-libc):

> /* #APP */

(x86)\avr8-gnu-toolchain\avr\include\util\delay_basic.h" 1
>       1: subi r24A,1
>       brne 1b
> ;  0 "" 2
> /* #NOAPP */

By no means I can see how __STC_HOSTED__ could get you in "A" after "r24". 
The revision logs of delay_basic.h and delay.h[.in] don't mention such a bug,
and my builds of 4.9.2 from around that time also look sane.  Also I never
came across a GCC bug which added additional "A" junk to operands.

The only issue with this is vor AVR_TINY where register class "w" is empty.
