But that wasn't working for the template case where we are considering the conversion at the point that the constructor needs the DMI instantiation, so it seemed like we were in a constructor already. And then when the other constructor tries to reuse the instantiation, it sees uses of the first constructor's parameters, and dies. So ensure that we get the CONVERT_EXPR in this case, too. PR c++/106890 gcc/cp/ChangeLog: * init.cc (maybe_instantiate_nsdmi_init): Don't leave current_function_decl set to a constructor. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/nsdmi-template25.C: New test.
