[Bug 1847036] Re: changeme.py crashed with SIGSEGV

[James Page]

This is the offending class:

    class in6_addr_U(ctypes.Union):
        _fields_ = [
            ('__u6_addr8', ctypes.c_uint8 * 16),
            ('__u6_addr16', ctypes.c_uint16 * 8),
            ('__u6_addr32', ctypes.c_uint32 * 4),
        ]
