             Bug #: 55537
           Summary: constexpr usage crashes the compiler
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: akrzemi1@gmail.com


Compilation of the following code causes the compiler to crash:

//// BEGIN
  constexpr int j = 0;

  constexpr int const& get() { 
    return (0, *&j);
  }

  constexpr int i = get();

  int main() { }
//// END

I get error message:
"internal compiler error: in adjust_temp_type, at cp/semantics.c:6400"

Even a slightly simpler example crashes:


//// BEGIN
  constexpr int j = 0;

  constexpr int const& get() { 
    return (0, j);
  }

  constexpr int i = get();

  int main() { }
//// END
