Re: [Boost-users] Crash when assign value to regex object

...

And QueryGreppers is a function pointer get from another dll, any comments about this?

Yes: better make sure you link against the dll version of the library, otherwise you will have multiple "versions" of the code in your application. Define BOOST_REGEX_DYN_LINK when building your application and dll's to do this (see http://www.boost.org/libs/regex/doc/configuration.html#linkage). If you link to other Boost libs then you have the same issue with them as well (defining BOOST_ALL_DYN_LINK will force all Boost libs to link against their dll versions). John.
