The symbols in your example are the result/ouput of demangling but the issue
reported here is with the symbols that are input into GDB.  There is more than
one way to represent the same specialization of a template (e.g., B<unsigned>
and B<unsigned int>, or A<2> and A<2u>, or even A<1 + 1>).  GDB should be able
to accept all of them and recognize they all refer to the same specialization.
