Hello,

  I also got bitten by this problem.

$ echo "int main () { ; return 0; }" > test.c
$ gcc -fno-strict-aliasing -g -g -O2   test.c
/usr/bin/ld: internal error in value_from_output_section, at
../../gold/reloc.cc:1519
collect2: ld returned 1 exit status

$ ld.gold -v
GNU gold (GNU Binutils for Debian 2.21.52.20110606) 1.11

If using ld.bfd instead of gold, it works

Anyway, I went ahead and applied Ian suggestion:

Which produces a successful linkage:
