Notice that in rot(), long D.1484_5 is unused and instead the 32-bit value
D.1482_3 is used.
BTW, what does "w*" mean?

16-bit, of course. In the s-file you can see that __usmulhisi3 is used. This
is a widening 16-bit unsigned * 16-bit signed multiplication and not correct
here.

Using the code from comment #7 the problem persists
$ avr-gcc -S -Os pr57503.c -mmcu=atmega8 -dP
long
func1 (unsigned char a, unsigned char b, int c)
{
unsigned ab = a * b;
return (long) ab * c;
}
The code is a bit different but still wrong:
func1:
; (insn 10 5 25 (set (reg:HI 18 r18 [orig:44 D.1450 ] [44])
; (mult:HI (zero_extend:HI (reg:QI 24 r24 [ a ]))
; (zero_extend:HI (reg/v:QI 22 r22 [orig:50 b ] [50]))))
pr57503.c:4 168 {umulqihi3}
; (expr_list:REG_DEAD (reg:QI 24 r24 [ a ])
; (expr_list:REG_DEAD (reg/v:QI 22 r22 [orig:50 b ] [50])
; (nil))))
mul r24,r22 ; 10 umulqihi3 [length = 3]
movw r18,r0
clr __zero_reg__
; (insn 25 10 26 (set (reg:HI 26 r26)
; (reg/v:HI 20 r20 [orig:51 c ] [51])) pr57503.c:5 82 {*movhi}
; (expr_list:REG_DEAD (reg/v:HI 20 r20 [orig:51 c ] [51])
; (nil)))
movw r26,r20 ; 25 *movhi/1 [length = 1]
; (insn 26 25 21 (set (reg:SI 22 r22)
; (mult:SI (sign_extend:SI (reg:HI 18 r18))
; (sign_extend:SI (reg:HI 26 r26)))) pr57503.c:5 231
{*mulhisi3_call}
; (expr_list:REG_DEAD (reg:HI 26 r26)
; (expr_list:REG_DEAD (reg:HI 18 r18)
; (nil))))
rcall __mulhisi3 ; 26 *mulhisi3_call [length = 1]
; (jump_insn 31 21 30 (return) pr57503.c:6 451 {return}
; (nil)
; -> return)
ret ; 31 return [length = 1]
Insn 26 sign-extends both inputs but R18 (unsigned ab) should be zero-extended.

Same applies to the 4.8 branch, again it is insn 26 that is wrong:
func1:
