HTTP Header Host ptr field not set

I noticed while lookup at cache scan that the host field of URLImpl is not set correctly.

the m_ptr_host field is 0x0 while the m_len_host is correct (14).

here is what it looks like:

$20 = {<HdrHeapObjImpl> =

, m_len_scheme = 4,
m_len_user = 0, m_len_password = 0, m_len_host = 14, m_len_port = 0, m_len_path = 0,
m_len_params = 27, m_len_query = 0, m_len_fragment = 0, m_len_printed_string = 0,
m_ptr_scheme = 0x0,
m_ptr_user = 0x7ffff2fe9d2f "http://www.google.com/intl/en_ALL/images/logo.gif HTTP/1.1\r\nHost: www.google.com\r\nUser-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6\r\nAccept: image/png,im"..., m_ptr_password = 0x0,
