I got

bash-3.1$ readelf -S -N  fzotl.o | grep ZN10otl_streamlsEPKc
  [257] .gnu.linkonce.t._ZN10otl_streamlsEPKc
  [258] .rel.gnu.linkonce.t._ZN10otl_streamlsEPKc
bash-3.1$ readelf -S -N fzconfig.o  | grep ZN10otl_streamlsEPKc
  [338] .gnu.linkonce.t._ZN10otl_streamlsEPKc
  [339] .rel.gnu.linkonce.t._ZN10otl_streamlsEPKc
  [340] .gnu.linkonce.r._ZN10otl_streamlsEPKc
  [341] .rel.gnu.linkonce.r._ZN10otl_streamlsEPKc
bash-3.1$ readelf -g fzotl.o fzconfig.o

File: fzotl.o

There are no section groups in this file.

File: fzconfig.o

There are no section groups in this file.
bash-3.1$ 

It means your gcc 4.1.1 was built with a very old binutils and it doesn't
support COMDAT group, which is needed to fix this bug. You have 2
choices:

1. Rebuild gcc 4.1.1 with the current Linux binutils.
2. Use a different Linux distribution with a proper gcc 4.1. FC6 is
OK.
