    auth-juniper.c: In function 'parse_input_node':
    auth-juniper.c:108:11: warning: ignoring return value of 'asprintf', declared with attribute warn_unused_result [-Wunused-result]
    auth-juniper.c:114:11: warning: ignoring return value of 'asprintf', declared with attribute warn_unused_result [-Wunused-result]
