I may be wrong, but I suppose he was talking about Set-Long-Jump and
Table-Driven.

You may find which one your compiler use, with the option =93 -v =94
passed to GCC.

If in the output, you see contains =93 --enable-sjlj =94, this means the
GCC compiler was configured to use Set-Long-Jump for exceptions,
otherwise, the most common implementation is the Table-Driven one, due
to its efficiency, beceause it does not cost any wasted overhead when
no exceptions are raised, unlike what it is with the Set-Long-Jump
(executables are just a bit bigger).
