Yes, it's apparently causing a stack fault due to an incorrect branch statement. The bug is already present in V4.119, while V4.112 is working correctly.

V4.112
Code:
00566:  ADD     W3,W13,W3
00568:  RETURN 
0056A:  MOV     W3,W13
0056C:  MOV     W2,W12
0056E:  MOV     W1,W11
00570:  MOV     W0,W10
00572:  RETURN 
00574:  MOV     W10,[W14+#8]
00576:  MOV     W11,[W14+#A]
00578:  MOV     W12,[W14+#C]
0057A:  MOV     W13,[W14+#E]
0057C:  MOV     [W14],W10
0057E:  MOV     [W14+#2],W11
00580:  MOV     [W14+#4],W12
00582:  MOV     [W14+#6],W13
00584:  RETURN 
00586:  MOV     W10,[W14]
00588:  MOV     W11,[W14+#2]
0058A:  MOV     W12,[W14+#4]
0058C:  MOV     W13,[W14+#6]
0058E:  MOV     [W14+#8],W10
00590:  MOV     [W14+#A],W11
00592:  MOV     [W14+#C],W12
00594:  MOV     [W14+#E],W13
00596:  RETURN 
00598:  ULNK   
0059A:  MOV     #1A,W5
0059C:  REPEAT  #7
0059E:  MOV     [--W15],[W5--]
005A0:  MOV     [--W15],W5
005A2:  RETURN 


V4.120
Code:
00566:  ADD     W3,W13,W3

00574:  MOV     W10,[W14+#8]
00576:  MOV     W11,[W14+#A]
00578:  MOV     W12,[W14+#C]
0057A:  MOV     W13,[W14+#E]
