Running under gdb: ... rlm_sql (sql): Attempting to connect rlm_sql_mysql #0 rlm_sql_mysql: Starting connect to MySQL server for #0 rlm_sql (sql): Connected new DB handle, #0 rlm_sql (sql): failed after re-connect rlm_sql (sql): Error retrieving group list rlm_sql (sql): Error processing groups; rejecting user rlm_sql (sql): Released sql socket id: 0 Program received signal SIGSEGV, Segmentation fault.
