            Bug ID: 20346
           Summary: Strang diagnostic on struct initializer in template
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: nicolasweber at gmx.de

    Classification: Unclassified

struct S { short inner_s; };

struct outer_struct {
  wchar_t arr[32];
  S outer_s;

template <class T>
void OpenFileSession() {
  outer_struct asdfasdf = {};

void foo() {

$ ~/src/llvm-build/bin/clang -c test.cc
error: cannot initialize an array element of type 'wchar_t' with an rvalue of
type 'wchar_t [32]'
test.cc:14:3: note: in instantiation of function template specialization
'OpenFileSession<int>' requested here

Note: No source location on the error. And gcc and msvc compile this code fine.
(At least the missing source loc should be fixed for sure.)
