Summary: suppose pure abstract function resolve error
Product: gcc
Version: 4.3.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: gvolozha...@mail.ru
class A {
public:
virtual ~A() {}
virtual void foo()=0;
};
class B {
public:
virtual ~B() {}
virtual void foo() { }
};
class C: public B, public A {
};
int main() {
C c;
c.foo();
return 0;
}
$ g++ o.cpp
o.cpp: In function ‘int main()’:
o.cpp:17: error: cannot declare variable ‘c’ to be of abstract type ‘C’
o.cpp:13: note: because the following virtual functions are pure within ‘C’:
o.cpp:4: note: virtual void A::foo()
o.cpp:18: error: request for member ‘foo’ is ambiguous
o.cpp:4: error: candidates are: virtual void A::foo()
o.cpp:10: error: virtual void B::foo()
$ gcc --version
gcc (Ubuntu 4.3.3-5ubuntu4) 4.3.3
the bug maybe fixed already when recent visibility bugs fixed
anytime please don't waste time for the answer, best regards
