This is not a bug. Define copy constructor for class One, like
One( const One& ) { num=++global; cout<<"One copy constructor"<<num<<endl; }
and see if it helps.

>Description:
When I want to throw class, which has other class inside, and
constructor copies some properties of given class -- it look like
destructors are called wrond. I guess code will explain it better:
--------------------------------------
#include <iostream.h>
int global;
class One {
public:
int num;
One() { num=++global; cout << "One " <<num<<endl; };
void Copy(One second_one) { cout << "Copy " <<num<<endl; };
~One() { cout << "~One "<<num<<endl; };
};
class Two {
public:
One my_one;
Two(One one) { my_one.Copy(one); };
};
int main()
{
One a;
try {
throw Two(a);
} catch (Two two) {
cout << "Ok"<<endl;
}
return 0;
}
--------------------------------------
It produces following output:
( g++ _test.cpp -o test )
11:12:39 ~/src/eval/src # ./test
One 1
One 2
Copy 2
~One 1
~One 1
~One 1
~One 1
~One 2
Ok
~One 2
~One 2
~One 1
You see, each destructor is called way more tnat once.
P.s.: It work in a same way with 2.95.3
As a side note: 3.0's g++ appears to be MUCH MUCH slower than 2.95.3
>How-To-Repeat:
Preprocessed file is ~600kb large.
Just take file from the above, and compile it with
g++ _test.cpp -o test
>Fix:
No ideas.
