--- Comment #1 from Arsen Arsenovi=C4=87 <arsen at gcc dot gnu.org> ---
<source>: In function 'main':
<source>:4:18: warning: operation on 'a' may be undefined [-Wsequence-point]
    4 |         if (a < a--) {
      |                 ~^~

the result is simply undefined (is the first `a' pre- or post-decrement?)=
