             Bug #: 53159
           Summary: Missing narrowing check
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: marc.glisse@normalesup.org


In this example, I get narrowing warnings for a and b but not c.

struct X
{
  constexpr operator int() { return __INT_MAX__; }
};
int f(){ return __INT_MAX__; }

signed char a { __INT_MAX__ };
signed char b { f() };
signed char c { X{} };
