C++14 Generic Template issue (misunderstanding?)

I have C++14 enabled in a code (a Qt5 project) similar to the following:

auto func = [&](auto p, auto pp) {
    if(!p)
        return;
    pp = p;
    p->init();
};
MyClass *p1;
...
func(p1, m_p);
m_p->doSomething();

After receiving:

internal compiler error: Segmentation fault

Debugging I found m_pdid not change after the call to func, as I was expecting. Does generic templates (auto) really works so? How do I go to change m_p in a code like that?
