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.

[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_' referenced in section `.gnu.linkonce.r._ZNSt3mapIiN5boost7variantIicdSs14ACE_Time_ValueNS0_6detail7variant5void_ES5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_EESt4lessIiESaISt4pairIKiS6_EEEixERSA_' of ./src/geneva/infra/messaging/ResponseMsg.o: defined in discarded section `.gnu.linkonce.t._ZNSt3mapIiN5boost7variantIicdSs14ACE_Time_ValueNS0_6detail7variant5void_ES5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_EESt4lessIiESaISt4pairIKiS6_EEEixERSA_' of ./src/geneva/infra/messaging/ResponseMsg.o

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