Comment:

 OK, can reproduce, but I don't have a fix that doesn't break something
 else.

 This is caused by wc_regex_traits.cpp and usinstances.cpp which pull in
 __declspec(dllexport) std::allocator<unsigned short>::allocator(), but
 then your source files result in std::allocator<unsigned
 short>::allocator() (without the dllimport) being defined and hence the
 clash.  In other words it's caused by MS's headers getting in a pickle and
 defining symbols differently depending what compiler options are used.

 There are two solutions:

 Manually add the regex source files to your project with the exception of
 cw_regex_traits.cpp and usinstances.cpp, or build everything with
 BOOST_REGEX_DYN_LINK defined and link to the regex dll rather than the
 static lib.

 HTH, John.
