apreq_handle_apache2 segfaults

[Maxim]

Hi all!

The following problem with my module:
wherever i try to call apreq_handle_apache2, my module leads to segfault
during request processing.
FOr example, I tried to do the following thing:

static int mod_tut1_fixups(request_rec *r)
{
        fprintf(stderr, "FIXUPS");
        req_h = apreq_handle_apache2(r);

        return DECLINED;
}

and this lead to segfault in every request. I don't know at what stage 
of request processing, but must be very early, because I didn't see that
"FIXUPS" message, which this hook where supposed to output.

Any example of actually using this apreq_hadle_request would be 
really-really helpful!

Thanks in advance!
