I just downloaded binutils-2.21.51.06.tar.bz2 from your repository on
kernel.org and built it myself, and I could reproduce the bug there.
The date part of the version number is different from your trace below,
though (and the date part agrees with what is in Fedora 15 Alpha):
: tazenda 135 ; nm symerr.elf
00000500 A __bss16_dwords
00001400 B __bss16_end
00001400 B __bss16_len
00001000 B __bss16_start
0000800f T __text16_end
00008000 T __text16_start
00008000 T _start
: tazenda 136 ; objdump -dw symerr.elf
symerr.elf: file format elf32-i386
Disassembly of section .text16:
00008000 <__text16_start>:

8005: b9 00 05 00 00 mov $0x500,%ecx
800a: 31 c0 xor %eax,%eax
800c: f3 a5 rep movsl %ds:(%esi),%es:(%edi)
800e: c3 ret
: tazenda 137 ; ld -V

: tazenda 138 ;
