Reproduces the bug
Compile attached file with
clang++ -std=c++11 -stdlib=libc++ TestFunctional.cpp -o TestFunctional
The relevant function:
void Capture(std::function<void (CDispatchTypeTag *)> const &_Function)
{
//auto Function = _Function; // Uncomment this and it works
auto fTest
= [_Function]()
{
_Function(nullptr);
}
;
}
The destructor and copy constructor is not called the correct number of times
unless the line above is uncommented.</pre>
