It seems that g++ (3.3.2, 3.3.3, gcc-3.4-20040107) duplicates user defined
constructors, destructors, etc.
Is this supposed to be?

cat > test.cpp <<EOF
struct A {
  A();
  A(const A&);
  A(int);
};


A::A(){}
A::A(const A&) {}
EOF
g++ -S test.cpp


This generates the following assembly code on my system:

        .file   "test.cpp"
        .text
        .align 2
.globl _ZN1AC1ERKS_
        .type   _ZN1AC1ERKS_, @function
_ZN1AC1ERKS_:
.LFB7:
        pushl   %ebp
.LCFI0:
        movl    %esp, %ebp
.LCFI1:
        popl    %ebp
        ret
.LFE7:
        .size   _ZN1AC1ERKS_, .-_ZN1AC1ERKS_
        .align 2
