One of major changes is 1.2.0 adopts lemon 1.59 (Wireshark 1.0.8 uses lemon
1.51).
I use 1.0.8 code base to do following experiments:
1. (OK) 1.0.8 from SVN (with lemon 1.51)
$ ./dftest "tcp fa"
Filter: "tcp fa"
dftest: "fa" was unexpected in this context.
2. (FAIL) 1.0.8 with lemon 1.59
$./dftest "tcp fa"
00000 CHECK_EXISTS tcp
00001 RETURN
However, I do not know why the lemon version matters.
