test case

According to C++ standard:

15.5 Special functions
The functions std::terminate() and std::unexpected() are used by the exception
handling mechanism for coping with errors related to the exception handling
mechanism itself. 

15.5.1 The std::terminate() function 
In some situations exception handling must be abandoned for less subtle error
handling techniques. 
These situations are:
when the exception handling mechanism, after completing the initialization of
the exception object but before activation of a handler for the exception calls
a function that exits via an exception

However, for the attached test case, control flow still goes to "catch"
