--- Comment #3 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
int main (void)
{
int x = 0, y [++ x], z [++ x];
__builtin_printf ("%d, %d, %d\n", sizeof x, sizeof y, sizeof z);
return 0;
}
$ cc1 -Wsequence-point test.c
test.c:3:27: warning: operation on ‘x’ may be undefined [-Wsequence-point]
int x = 0, y [++ x], z [++ x];
^
I'll let someone else with more knowledge of the standard to decide if the
warning is correct or not.
