--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
The -Wrestrict warning (new in GCC 7) points out this bug. Unfortunately, the
option is not in -Wall or -Wextra and must be explicitly enabled so few users
will benefit from it.
$ gcc -S -Wrestrict t.c
t.c: In function ‘main’:
t.c:6:13: warning: passing argument 1 to restrict-qualified parameter aliases
with argument 2 [-Wrestrict]
memcpy (&i, &i, sizeof i);
