Comment (by fgiraldeau):

 The error root is put_union. Here is the union lens to process.
 {{{
            L_UNION
               |
         -------------
         |           |
       L_REC       L_DEL
         |
        ...
 }}}

 On line put_union.c:477 the call to applies(lens, state) returns true for
 both the L_REC and L_DEL. By switching the order in the union, the L_DEL
 is processed before L_REC, and the output is correct.
