You can look up in the device datasheet to see how much RAM it has.

FWIW: As things currently appear, this breakdown is not restricted to the
-mmcu=avr25 multilib-variant, but affects all RTEMS multilibs.

There are already spill fails reported for AVR, it's a known problem.
At this point it cannot be said if this PR is really

I can also reproduce the bug with 4.2.0-20070501.
It also is related to optimization levels. Newlib is being compiled with -O2,
which triggers this breakdown. Using -O1 or -Os to build init.c lets the

This is the minimised *.c having been extracted from newlib's file exposing the

Thanks, yes, 15342 looks very similar.
And yes, it does not ice at -O2 (This is what I had meant by writing it does
not ice at optimization levels 3).

Eric, do you happen to know when this bug first appeared?
I noticed it for the first time shortly before submitting this PR (Opened:
2004-03-17; cf. above;).
I don't recall

1. The PR is against 3.4-branch, because this is what I am using, what I tested
the patch with and what I am reporting the bug against.
2. The patch applies to HEAD without changes.
3. Why is GCC asking

1. I am used to my patches being ignored :(
Therefore I usually attach them to a PR they are trying to solve to prevent them
from being ignored.
