           Summary: no error calling non-const method on const object
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: nlewycky at google.com

  struct Struct {
   void Func() {}

  int main() {
   const Struct s = {};
   void (Struct::*func_ptr)() = &Struct::Func;
   return 0;

's' is const, then we call a non-const method on it. Clang emits no error, GCC
and Comeau do. Here's GCC:

b3410310.cc: In function ‘int main()’:
b3410310.cc:8: error: invalid conversion from ‘const Struct*’ to ‘Struct*’
