I think I have found the problem. It is related to the patch Ed sent.
The new LD looks like it automagically turns on the --build-id option.
I have not found out how turn it off.
When this option is used it generates the .note.gnu.build-id section.
When this section was discarded in the first ld pass (linuxbios_rom.ram
creation) it was causing the segmentation fault crash.
It looks like this same option is being called again when crt0.o is
linked to create linuxbios. I have added the .note.gnu.build-id section
to the .id section in the ldscript.ld file.
SECTIONS {
. = (_ROMBASE + ROM_IMAGE_SIZE - 0x10) - (__id_end - __id_start);
.id (.) : {
*(.id)
*(.note.gnu.build-id)
}
This has gotten me past the second crash but now linuxbios.strip is
crashing.
nm -n linuxbios | sort > linuxbios.map
objcopy --gap-fill 0xff -O binary linuxbios linuxbios.strip
objcopy: linuxbios.strip: Bad value
objcopy: linuxbios.strip: Bad value
make[1]: *** [linuxbios.strip] Error 1
So this does not look like a ld problem, but an added feature to ld is
causing us grief. If anyone can figure out how to turn this option
off, that may fix all of this without any patches... :-)

Unfortunately, it is still broken under Fedora 8.
V3 works, it is just V2 that is having these linking problems. This
patch makes things better, and it at least gives us a more descriptive
error than just a segmentation fault.
This at least gives me a good starting point to debug from .. I think
as soon as we get a stable version that should be the patch..
Please file a bug with the binutils guys. If they don't know ld is
broken, they can't fix it.
