           Summary: std::string as static member
           Product: gcc
           Version: 3.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: renz at renzresearch dot com
                CC: gcc-bugs at gcc dot gnu dot org

I think I have isolated a problem in the following 20 lines.  This program 
compiles fine, but the executable causes Segmentation fault (core dumped).  
Each of these points is essential to reproduce the fault:

class a<T> must be a template class;
class a<T> must have std::string as its static member;
class b must have a<T> as its static member;

The program crashes when the static member of class a is accessed.

#include <string>
#include <iostream>
using namespace std;

template <class T> class a {
   public:
      a() {cout << s << endl;}
      static string s;
};
template <class T> string a<T>::s("bug");

class b {
   public:
      b() {}
      static a<int> t;
};
a<int> b::t;

main() {
   const b bob();
   return 0;
}

This is a log of compilation: (but I don't know where to attach the .ii file)
