Thanks Eric , that was it.
Unfortunately it is only linker WARNING and easily missed during
compilation.

Subject: Re: [avr-gcc-list] Bug35013 - Incomplete check for
pm() annotation
Note that this bug is also related to:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27192
which has similar issue generating "byte address" instead of word
address. Oddly my patch appears to fix that without problem, using :
45 0014 80E0 ldi r24,lo8(pm(foo+512))
46 0016 90E0 ldi r25,hi8(pm(foo+512))
47 0018 9093 0000 sts (q)+1,r25
48 001c 8093 0000 sts q,r24
So it would appear problem with pm(foo+1) is more complicated than it
appears.
Ideas?
Functions are word aligned (16-bits). Does 'foo' evaluate to a pointer
to word? Or does it evaluate to a pointer to a byte, which when adding
one and then made into a pointer to flash (word aligned) doesn't give
any meaningful object?
