The bug does not manifest itself with the default compiler and linker on a
recent version of Debian Testing:

$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-linux-gnu/4.5.2/lto-wrapper
Target: x86_64-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Debian 4.5.2-11'

Thread model: posix
gcc version 4.5.2 (Debian 4.5.2-11) 

$ ld.gold -v
GNU gold (GNU Binutils for Debian 2.21.0.20110327) 1.11

$ ld -v
GNU ld (GNU Binutils for Debian) 2.21.0.20110327

so perhaps this has been fixed in GCC 4.5.3 and ld 2.21.
