I just tried with sdcc 2.8.9 #5392. I compiled your function using sdcc
-mz80 test.c. I could not reproduce the bug. I get the following code:
;test.c:10: } while (maxlen && c1 && c2 && c1==c2);
ld a,e
or a,d
jr Z,00114$
xor a,a
or a,c
jr Z,00114$
xor a,a
or a,b
jr Z,00114$
xor a,a
or a,-5 (ix)
jp NZ,00112$
00114$:
