--- Comment #4 from stepik-777 at mail dot ru 2012-11-24 10:03:55 UTC ---
You can use !this->m_barbar intead of !m_barbar as a workaround.

This bug is still present in 4.7.2.

template<typename T>
struct Struct
{
    int member;

    Struct()
    {
        [=]{ !this->member; }; // this works
        [=]{ !member; }; // internal compiler error: Segmentation fault
    }
};
