.... or at least it would, if VC++ implemented standard-conforming
handling of exceptions specifications, which it doesn't (and IMO
never should).
Based on Handling Exceptions article, throwing a non-declared
exception is OK by C++ standards.
According to the C++ standard, throwing an exception that's not listed in
the exception specification from within a function that has an exception
specification will call unexpected(), the default behavior of which is to
call terminate().
If the function has no exception specification then you can throw anything
(i.e. no specification is equivalent to throw(*) - if that were legal, not
equivalent to throw()).
VC++ generally ignores exception specifications with the exception that a
throw() specification will actually cause the compiler to omit exception
handling code around calls to that function - it treats the throw()
exception specification as being equivalent to __declspec(nothrow) - almost
the diametrical opposite of what the standard mandates.
