Using any simple test program, do this on a 32bit host (64bit hosts tend not to
crash reliably here)
$ avr-gcc -mmcu=attiny2313 avr_test.c -c
$ avr-ld -m avr2 -o avr_test.hex /opt/cross/avr/lib/crttn2313.o --oformat ihex
avr_test.o
BFD 2.17.50.0.8 20061201 internal error, aborting at ../../bfd/linker.c line
2397 in set_symbol_from_hash
I tracked that back to one specific patch added in August 2006:
cvs -d :pserver:[EMAIL PROTECTED]:/cvs/src co -D '2006-10-17 15:41'
binutils
- is good
cvs -d :pserver:[EMAIL PROTECTED]:/cvs/src co -D '2006-10-17 15:42'
binutils
- crashes.
The Changelog of the patch has this:

elf32-avr.c is not in the list. Can someone please help extending this patch
to cover also avr targets?
Thanks,
