           Summary: Rejects-valid/potential miscompile in edge case with
                    templates and initializer-list
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: sharparrow1 at yahoo.com
                CC: llvmbugs at cs.uiuc.edu, dgregor at apple.com


Testcase:
struct X { int a, b; };
template<typename T> int foo(T x) {
  X i[] = { 1, x, { 3, 4 } };
  return sizeof(i);
}
void g() { X i = { 1, 2 }; foo(i); }

This code is valid, but clang rejects it.  More complicated cases involving
conversion operators could be miscompiled.
