the same happens to me in case of I link
code compiled with -g and other code compiled with -O2.
I think it is just a warning that the
linker picks up a certain copy of code which is available more than once.

Odd linker errors that somehow involveboost::variant
[NOTE : this is using boost v1.32. I am forced to use this
version]
In the code I am trying to compile I have a boost variant defined as:
boost::variant<int, char, double, std::string, ACE_Time_Value>
and it is used in several different ways. This project compiles and links
fine using debug settings, essentially the -g flag in gcc, however whenever I
try to compile without that flag I get the following error, repeated hundreds
of times:
`.gnu.linkonce.t._ZNSt3mapIiN5boost7variantIicdSs14ACE_Time_ValueNS0_6detail7variant5void_ES5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_EESt4lessIiESaISt4pairIKiS6_EEEixERSA_'

Google is not helping diagnose the problem at all. I am wondering if
anyone here can point me in the right direction.
