I think the problem is in this code from DBD::Sybase:

    if(imp_dbh->chainedSupported) {
        CS_BOOL value = CS_FALSE;

        if(dbis->debug >= 2)
            PerlIO_printf(DBILOGFP, "    syb_db_login() -> checking for
chained transactions\n");
        retcode = ct_options(connection, CS_SET, CS_OPT_CHAINXACTS, 
                             &value, CS_UNUSED, NULL);
        if(retcode == CS_FAIL) {
            imp_dbh->doRealTran = 1;
            imp_dbh->chainedSupported = 0;
        }
        if(dbis->debug >= 2)
            PerlIO_printf(DBILOGFP, "    syb_db_login() -> chained
transactions are %s supported\n", retcode == CS_FAIL ? "not" : "");
    }

It's the ct_options() call that causes the segfault, apparently.
