             Bug #: 51666
           Summary: NSDMI parse fails for template'd intializer
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: miles@gnu.org


The following code:

   template<typename T, typename U>
   struct tuple
   {
     tuple(T, U) { }
   };

   struct Y
   {
     tuple<int, int> tt = tuple<int, int>{1, 2};   // *error*
   };

Fails with a parse error in gcc 4.7 20111210:

   $ g++-snapshot -c -std=c++11 nsdmi3.cc
   nsdmi3.cc:9:36: error: expected unqualified-id before 'int'
   nsdmi3.cc:9:31: error: wrong number of template arguments (1, should be 2)
   nsdmi3.cc:2:9: error: provided for 'template<class T, class U> struct tuple'

   $ g++-snapshot --version
   g++ (Debian 20111210-1) 4.7.0 20111210 (experimental) [trunk revision
182188]

Thanks,

-miles

I bet a beer this is related to PR 57 (one of the most duplicated bugs in
bugzilla).  In fact the same work around fixes this testcase.  
Jason can you comment if DR 325 applies to NSDMI and not just default
arguments?

Ah yes, the latest note on DR 325 confirms the same issue exists with NSDMIs
