<pre>clang-cl -v
clang version 4.0.0 (trunk)
Target: i686-pc-windows-msvc
Thread model: posix
Using the following cpp files as a test file :
<a href="https://github.com/Microsoft/clang/blob/master/test/SemaCXX/warn-weak-vtables.cpp">https://github.com/Microsoft/clang/blob/master/test/SemaCXX/warn-weak-vtables.cpp</a>
I Get the following output:
warn-weak-vtables.cpp(34,7): warning: 'Parent' has no out-of-line virtual
method definitions; its vtable will be emitted in every translation
unit [-Wweak-vtables]
class Parent {
(It prints the warning for 'A','Parent','Derived' ...)
As I understand it, it shouldn't happen (Parent has an out-of-line virtual
destructor, Derived has getFoo that is out-of-line...)</pre>
