If moving above code snip to the end of function will cause another
problem....evaluation of (m_base != (void* )address) is false always.

my suggest is m_base is the return value of mmap(...) not the user
want. but get_address() return m_base + m_extra_offset not m_base.

it's more clear than use modified m_base everywhere.

sorry for the wrong information last email.
