You need to ensure that the Boost libraries you link against are built the 
same way as your application: in this case that means linking against the 
thread safe versions of the libraries, so 'libboost_thread-sw-mt-1_33_1' 
looks right but 'libboost_regex-sw-1_33_1' should probably be 
'libboost_regex-sw-mt-1_33_1' and likewise 'libboost_date_time-sw-1_33_1' 
should probably be 'libboost_date_time-sw-mt-1_33_1'.
