I dug up some more info.  First, user of the missing symbol is string-inst.o. 
 The second issue I see is that there is only one template arg for 
common_pool_policy.  Yet all the code I can find shows two args.

So one question is whether partial specializations will result in the compiler 
not printing out the template arg when it sees a problem.

BTW, if I pull the symbol out of string-inst.o and print it with c++filt, it 
is missing the second template arg.
