            Bug ID: 115553
           Summary: Memory leak in openmp.cc's gfc_free_expr_list -
                    gfc_expr not freed
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
                CC: jakub at gcc dot gnu.org
  Target Milestone: ---

It looks as if a 'gfc_free_expr (list->expr)' is missing before the 'free' call
in:

However, I have not checked whether there are cases where only the list needs
to be removed and the gfc_expr is used (and later freed elsewhere).

/* Free expression list. */
void
gfc_free_expr_list (gfc_expr_list *list)
{
  gfc_expr_list *n;

  for (; list; list = n)
    {
      n = list->next;
      free (list);
    }
}
