Does your linker script still have the usual line:

   .data    : AT (ADDR (.text) + SIZEOF (.text))

That sets the LMA for .data to follow on from .text, so ld really ought
to be checking that this also fits into the output section for .text
(i.e. text) just as you expect.

As the hour is approaching 2 a.m. here, I may regret in the morning
saying that it definitely is a bug, but it doesn't look good.

Do you have an old version of ld to hand, for comparison? The binutils
maintainers should be able to be won over without a demonstrated
regression, but it could possibly save some discussion.

It may possibly be avr-specific code which is the problem though, and
that puts it back in our camp. (Though I can't immediately see a case
for that.)
