             Bug #: 55944
           Summary: [C++11] static local member with constexpr c'tor
                    causes ICE
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: daniel.kruegler@googlemail.com


While testing bug 55931 on gcc 4.8.0 20130106 (experimental) using the compiler
flags 

-Wall -std=c++11 -pedantic

the following program causes an ICE:

//-----------------------------------
template<class T>
struct Test
{
  constexpr Test(T val) : value(val) {}
  static void test()
  {
    static constexpr Test<int> x(42); // ICE
  }
  T value;
};

int main()
{
  static constexpr Test<int> x(42); // OK
  Test<double>::test();
}
//-----------------------------------

"7|internal compiler error: tree check: expected target_expr, have cast_expr in
check_initializer, at cp/decl.c:5699"

This program should be accepted.
