Hi netters!
I get a core dump from the following code, if in separate files,
although everything goes fine if they are grouped together.
-b.h--------------------------------------------------------
class B {
public:
virtual ~B() = 0;
};
-b.C--------------------------------------------------------
#include <iostream.h>
#include "b.h"
B::~B() {
cout << "B::~B() for: " << this << endl;
}
-main.C-----------------------------------------------------
#include <iostream.h>
#include "b.h"
class A: public B {
public:
~A();
};
A::~A() {
cout << "A::~A() for: " << this << endl;
}
main() {
A fred;
cout << "That's all Folks!..." << endl;
return 0;
}
-test--------------------------------------------------------
> ab
That's all Folks!...
A::~A() for: 0x68fad4d8
Abort(coredump)
...and under gdb:
Program received signal 6, Aborted
0x158c0 in ___stdio_unsup_1 ()
As I said, this is ok:
-main.C------------------------------------------------------
#include <iostream.h>
class B {
public:
virtual ~B() = 0;
};
B::~B() {
cout << "B::~B() for: " << this << endl;
}
class A: public B {
public:
~A();
};
A::~A() {
cout << "A::~A() for: " << this << endl;
}
main() {
A fred;
cout << "That's all Folks!..." << endl;
return 0;
}
------------------------------------------------------------
Best Regards!
