Attached is approx 30 sec of output from the following command:

# /usr/src/nut-2.2.1/drivers/usbhid-ups -u root -DD -a trippy > poop.out 2>&1

No extra code or printf's are in the the above exec.

Note that "dstate_init: sock..." does not appear in the output.

FYI: In one test, add the following to dstate_init... It's almost as if 
it is not even being called???

void dstate_init(const char *prog, const char *port)
        char    sockname[SMALLBUF];

        fprintf(stderr, "@@@2 i made it here!\n"); <<<--- i never see this
        exit(1); <<<------- this does not cause it to exit???

        /* do this here for now */
        signal(SIGPIPE, SIG_IGN);

        fprintf(stderr, "@@@3 i made it here!\n");

        if (port != NULL)
                snprintf(sockname, sizeof(sockname), "%s/%s-%s",
                        dflt_statepath(), prog, port);
                snprintf(sockname, sizeof(sockname), "%s/%s",
                        dflt_statepath(), prog);

        sockfd = open_sock(sockname);

        upsdebugx(2, "dstate_init: sock %s open on fd %d", sockname, sockfd); <<<--- not in the debug output???
