This is what I get on x86_64:

nm libstdc++.a | grep
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE
 U
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE
 U
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE
 V
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE

thus, seems a target problem to me.

As shown, these symbols are exported as "u":

`u'
  The symbol is a unique global symbol.  This is a GNU
  extension to the standard set of ELF symbol bindings.  For
  such a symbol the dynamic linker will make sure that in the
  entire process there is just one symbol with this name and
  type in use.

In the hope it helps, this is what I get from
libstdc++-v3/src/.libs/libstdc++.a:

$ c++filt _ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE
std::num_get >
>::id

$ nm libstdc++.a | grep
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE
 U
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE
 u
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE

Before we do anything here, you should try to explain why the problem happens
only on alpha, because on x86_64 it doesn't and those symbols are exported
("V"). Are the symbols exported on alpha? Are we **really** sure that aging

The testcase:

#include 
#include 

int
main (int argc, char *argv[])
{
std::string myStr = "Hello, World!";
std::cout << myStr << std::endl;
return 0;
}
