Milter-greylist

I tried to run milter-greylist on my x86-64 system, with libspf.
2.0.2 failed with SPF2 (didn't try SPF1)
2.1.3 failed with SPF1 and SPF2.

System: linux 2.6.15.4, debian-testing, x86-64 (Sempron).

When running 2.1.3 with SPF1 in gdb (with -D  -u smmsp) it properly
checks several emails, and then fails with:
milter-greylist: k1MJMoVE009106: skipping greylist because recipient

I would like to set breakpoints, but don't know where, I cannot find
where the "mi_stop=1" is printed.

When running 2.0.2 or 2.1.3 with libspf2, I get a segfault.
Running 2.1.3 with libspf2, I get this (from gdb):

=>      SPF_request_query_mailfrom(spf_request, &spf_response);
Program received signal SIGSEGV, Segmentation fault.

(gdb) up
#1  0x00002aaaaabcd5f2 in SPF_record_expand_data () from
/usr/lib/libspf2.so.2

(Haven't yet installed the source of libSPF2 to find where it is).

I'm wondering if these errors are known (with a known fix), or if it's
worth trying to figure out what the segfaults are etc.
And, if so, should I try 2.0.2 or 2.1.3?

Thanks,
