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'

this conversion, or the operator cannot be called
