This is a situation I have been concerned about.  New versions of
the library include code to address this.  However, your code
might invoke an assert trap rather than failing as it does now. My
argument is that this is an improvement - not every one agrees
however.

My recommendation is

a) upgrade to lastest boost released
b) structure your code so that code is not repeated across DLLS
