Bug ID: 37833
Summary: Abstract class in function return type
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
The code is as follow:
template<typename T>
struct S{};
struct A
{
virtual void f() = 0;
};
int main()
{
S<A(int)> s;
}
An abstract class shall not be used as a function return type, but clang++
accepts the code.
The code comes from a gcc bug report
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51184).
A previous version of gcc also accepts the code, but it is fixed already.
