[lldb-dev] unaligned cast in TCPSocket::Connect

TCPSocket::Connect has this line:

            host_str = ::inet_ntoa (*(struct in_addr


host_entry->h_addr_list is a char**, while struct in_addr contains a
uint32_t. Casting like this (char * to uint_32t *) could cause a bus error
on systems that don't allow non-aligned loads. I think we need to memcpy the
data into a struct in_addr variable.


Anyone have any thoughts on this?
