>Description:
Apparently binutils as of 4.1-RELEASE break static constructors in C++
for GCC 2.95.x and GCC-current. Both work fine (w/o FreeBSD patches) on
FreeBSD 3.x and also GCC 2.95.2 as shipped with 4.1-RELEASE is fine.

I assume that there is a problem (change) in binutils on 4.1-RELEASE that
causes this breakage and that has been fixed (also made) in the imported
version of GCC?
>How-To-Repeat:
Compile and run the following small C++ program with either GCC 2.95.2
(original version, w/o FreeBSD patches) or GCC-current and you'll get
a core dump as the static constructor is not invoked.

GCC as shipped with 4.1-RELEASE is not affected.

-------- cut --------
#include <map>
#include <iostream>

struct NAMESTABLE
    {
    map<int,int> lookup;

    NAMESTABLE()
        : lookup()
        {
        cout << "constructor" << endl;
        }

    void add(const char *s, const int &item)
        {
        cout << s << endl;
        lookup.insert(pair<int,int>(item,0));
        }
    };

NAMESTABLE q;

int main() {
    NAMESTABLE p;
    p.add("auto",1);
    q.add("static",1);
    }
>Fix:
1. Fix (the local copy?) of binutils.
2. If it is a GCC bug (which I don't believe) submit the change back
   to the GCC maintainers.
