Gaby, I'm really eager to understand more about this...

My naive understanding of such matters is based on object files and 
linking with libraries. If there are no instantiations  present in the 
libstdc++.so binary (this I have verified troughly) how could the whole 
break as an effect of moving the members??

Ciao, Paolo.

P.S. Of course 'til the issue is /completely/ clarified I will not move 
the patch to the branch!
