--- Comment #5 from Jonathan Leffler <jonathan.leffler at gmail dot com> ---
The link
https://gcc.gnu.org/onlinedocs/gcc-13.2.0/gcc/C_002b_002b-Dialect-Options.h=
tml#index-Wuse-after-free
is to the "Options Controlling C++ Dialect".

I was using the C compiler, not the C++ compiler, so it is not at all obvio=
us
that I should look at that page =E2=80=94 in fact, that page is irrelevant =
to users of
the C compiler.

The information there should be either copied to the C "Warnings Options" p=
age,
or linked to from the C page, where -Wuse-after-free is only mentioned and =
not
defined.

Incidentally, under "-Wuse-after-free=3D1" on the C++ page, there's a typo =
in:

whether or not the call resulted in an actual reallocatio of memory

The 'n' is missing from 'reallocation'.=
