[Bug c++/17037] New: static map in template crash on runtime when inserting


I use the mingw version of g++ 3.4.1 on windowsXP
Maybe my code is wrong but g++ should have say it before compiling and linking.
Don't know if this bug is on other version.
Here is how to reproduce the bug :

#include <iostream>
#include <map>

using namespace std;

struct ltstr
{
  bool operator()(const char* s1, const char* s2) const
  {
    return strcmp(s1, s2) < 0;
  }
};

template <typename _dxty>
class f
{
    public:
    typedef map<const _dxty*, int, ltstr > mapType;

    protected:
    static mapType months;

    public:
    f()
    {
      cout << "beginning" << endl;
      months["toto"] = 1;
      
      cout << "crash when inserting, same thing with insert" << endl;
    }
};

// this is maybe wrong but it compile and link this way
template class f<char>;
template <> f<char>::mapType f<char>::months;

int main()
{
    f<char> a;
    cin.get();
    return 0;
}
