            Bug ID: 26396
           Summary: [3.8 regression] -Wreturn-stack-address false
                    positives
           Product: clang
           Version: 3.8
          Hardware: PC
                OS: Linux

Since very recently we're getting false-positive -Wreturn-stack-address
warnings:

template <class T>
class QMap
{
public:
    T value(const T &t = T()) const
    {
        return t;
    }
};

struct A {};

void test()
{
    QMap<A*> map;
    map.value();
}

$ clang++ testcase.cpp  -c
testcase.cpp:7:16: warning: returning address of local temporary object
[-Wreturn-stack-address]
