--- Comment #5 from Eric Gallager <egallager at gcc dot gnu.org> ---
One thing to consider now that GCC has a static analyzer is that putting the
kind of useless "if" in question before a "free" can make the analyzer shut up
about possible double-free warnings, so if this were to become its own
diagnostic, there might be separate diagnostics that prompt users to do
opposite things...
