Hu? I just tried it.

pcm 2.636 does.

Did you perhaps forget the colon after the label? Most assemblers I
am used to don't require (or even accept) colons after the label. But
the ccs builtin assembler does. If you for example write
fini   retlw 2
you get the aforementioned error message.
Write
fini: retlw 2
instead.
