AFAICT, there is no leak.
gfc_free_statement (gfc_code *p)
{
if (p->expr1)
gfc_free_expr (p->expr1);
if (p->expr2)
gfc_free_expr (p->expr2);
gfc_free_expr (gfc_expr *e)
{
if (e == NULL)
return;
if (e->con_by_offset)
splay_tree_delete (e->con_by_offset);
free_expr0 (e);
gfc_free (e);
}
The last gfc_free(e) should prevent a leak.
