            Bug ID: 107624
           Summary: Wrong code with static operator ()
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jakub at gcc dot gnu.org
  Target Milestone: ---

In:
struct S {
  static void operator() (int);
  static void baz (int);
};
S &foo (int);

void
bar ()
{
  foo (0) (0);
  foo (1).baz (1);
}
we transform the latter into *foo (1), S::baz (1), but the former into just
S::operator() (0) - the side-effects on the postfix-expression are gone.
Shouldn't we add that somewhere as COMPOUND_EXPR when we select a static
operator() (ditto for static operator[])?
