The main difference between the macros and the keywords is
that the macros "automatically" delete a caught exception
when the exception goes out of scope. Code using the
keywords does not; exceptions caught in a catch block must
be explicitly deleted. Mixing macros and C++ exception
keywords can cause memory leaks when an exception object is
not deleted, or heap corruption when an exception is
deleted twice.

Answer / mullaikani

The major difference between the macros and the keywords is
that code using the macros "automatically" deletes a caught
exception when the exception goes out of scope. Code using
the keywords does not, so you must explicitly delete a
caught exception.
