Unexpected exception is an error for any statement, for any tool. Common 
rule is that execution monitors deals with it (like in case above). 
BOOST_CHECK_THROW checks that particular exception gets thrown. There are 3 
possible outcome:
1. No exception is thrown - error is reported by the tool
2. Expected exception is thrown - no error is reported
3. Unexpected exception is thrown - error is reported by test case monitor 
(the same would happened if an unexpected exception would happened in any 
other place)

Do you think this particular tool needs to catch all unexpected exceptions? 
But in this case no information for these exceptions would be reported.
