Confirmed, this reduced test should not abort but does:

struct X
{
    X() { __builtin_abort(); }
};

union Y
{
    // N3291=11-0061 12.6.2/8 says no initialization of
    // of other variant members (i.e. m_x) should
    // be performed.
    Y( )
        : m_char1{ }
        { }

    struct
    {
        char m_char1;
    };

    X    m_x;
};

int main()
{
    Y y;
}
