Major Description
ATS version 6.2.0 segment fault error while checking config using traffic_server -Cverify_config
It occurs after "INFO: Successfully loaded plugin.config"
only entry in ssl_multicert.config is as below,
dest_ip=* ssl_cert_name=fullchain1.pem ssl_key_name=privkey1.pem
gdb --args traffic_server -Cverify_config
(gdb) run
yields
INFO: Successfully loaded plugin.config
Thread 1 "traffic_server" received signal SIGSEGV, Segmentation fault.
0x0000000000000000 in ?? ()
(gdb) print SSLConfigParams::load_ssl_file_cb
$1 = (load_ssl_file_func) 0x0
