Nested loop in temporary definition causes exception -60 (FREE).

3 0 do i . loop 
0 1 2  OK
3 0 do 3 0 do i . j . loop loop
 Exception #-60

Works fine from normal definition

: test 3 0 do 3 0 do i . j . loop loop ;
test
0 0 1 0 2 0 0 1 1 1 2 1 0 2 1 2 2 2  OK

Also works inside quotations:

: test1 [: 3 0 do 3 0 do i . j . loop loop ;] execute ;
 OK
test1
0 0 1 0 2 0 0 1 1 1 2 1 0 2 1 2 2 2  OK

For some reason, the first LOOP is eating way more than its fair share of entries from the stack.

showstack
{ 0 : } OK
3 0 do 
Starting temp def... { 5 : 3 0 81FD7B 81FD7B 81FD84 } [OK]
3 0 do
{ 6 : 3 0 81FD7B 81FD7B 81FD84 81FD98 } [OK]
loop
{ 3 : 3 0 81FD7B } [OK]
loop
Ending temp def... { 4 : 3 0 2 4 } Exception #-60 
clear
{ 0 : } OK
3 0 do
Starting temp def... { 5 : 3 0 81FD7B 81FD7B 81FD84 } [OK]
3 0 do
{ 6 : 3 0 81FD7B 81FD7B 81FD84 81FD98 } [OK]
loop
{ 3 : 3 0 81FD7B } [OK]
[ 81FD7B 81FD84 ]
{ 5 : 3 0 81FD7B 81FD7B 81FD84 } [OK]
loop
Ending temp def... { 6 : 3 0 81FD7B 81FD7B 4 4 }{ 0 : } OK
