           Summary: ICE on illegal code: initialising a static data member
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: o dot kullmann at swansea dot ac dot uk
                CC: gcc-bugs at gcc dot gnu dot org

#include <limits> 
  template <class T> struct X { 
    static const int max = std::numeric_limits<int>::max(); 
    X() : m(max) {} 
    int m; 
  }; 
  template <class T> const int X<T>::max; 
int main() { X<int> x; } 
 
compiled with g++ version 3.3.1 (without options) yields 
internal compiler error: Segmentation fault 
 
This error doesn't occur with version 3.3 or 3.2.1, since these versions 
do not detect the invalid non-constant initialisation within the class. 
 
The code 
 
#include <limits> 
  template <class T> struct X { 
    static const int max = std::numeric_limits<int>::max(); 
  }; 
  template <class T> const int X<T>::max; 
int main() { X<int> x; } 
 
compiles with g++ version 3.3.1 although it is invalid.
