When I try this (on trunk) I get:

1>.\main.cpp(93) : error C2664: 'boost::diagnostic_information' : cannot 
convert parameter 1 from 'my_exception' to 'const boost::exception &'
1>        Reason: cannot convert from 'my_exception' to 'const 
boost::exception'
1>        No user-defined-conversion operator available that can perform 
this conversion, or the operator cannot be called
