And we need another 2461 bytes increase due to the new compiler. Just in
case anyone wonders which compiler causes continuous size increases:

gcc version 4.3.0 20080117 (experimental) [trunk revision 131592] (SUSE Linux)

Nak.  This is a more serious problem:

My system is:
gcc version 4.1.3 20070929 (prerelease) (Ubuntu4.1.2-16ubuntu2)

My sections are as follows:
.ram start 0xfffc0000 size 0x10098
.rom start 0xfffd0098 size 0xfac8

On the log from abuild, we can interpolate the results.  .ram start is


Section .id [00000000ffffefd2 -> 00000000ffffefef] overlaps section .rom
[00000000fffedd7c -> 00000000fffff96f]

We see that the .ram is (0xfffedd7c - 0xfffd0098) 122084 bytes larger on
the abuild machine then it is on my machine.   That certainly isn't because
of little changes in the compiler.  And .rom too has an increase,
(0xfffff96f - 0xfffedd7c = 72691), which is 8491 bytes larger then my box.

.id start 0xfffefd2 hardcoded, and .rom starts immediately after .ram. So, based on this line:

That is way outside the expected variation.

If you tell me how I can help, I'll be glad to do it.

Something is amiss here, and I need to put my head down with Stefan and figure it out. But in the meantime, hiding the problem isn't going to help

anybody.

Downgrading gcc on the official build machine would probably shed some
light on the situation.

How so? It will just remove the issue until the new gcc becomes widely usable.
