No ideas I'm afraid.  There is no w64_regex_traits: the w32_* version is 
intended for all Windows platforms.

Things to try:

1) Make sure you're actually linking to the 64-bit lib's, are the 32-bit 
ones lurking on anywhere on your hard drive and getting picked out instead?
2) Try defining BOOST_REGEX_NO_LIB when building your test app and adding 
all the regex source files directly to the app's project.  If this succeeds 
it indicates that the lib's you're linking against aren't correctly built.
3) If (2) fails you could try again with BOOST_REGEX_NO_EXTERNAL_TEMPLATES 
defined (the errors all relate to template instantiations that are normally 
placed in the lib file).

Oh and one other suggestion: are you selecting the lib to link against 
manually rather than let the auto-link code select it by any chance?  You 
could see errors like that if you link against the regex dll import lib, 
without defining BOOST_REGEX_DYN_LINK so it knows to add 
__declspec(dllimport) to the codes defs (or vices versa: setting that define 
then linking against the static link lib).

HTH, John.
