fangpei updated HAWQ-1494: -------------------------- Description: When I execute a specific sql, a serious bug can happen every time. (Hawq version is 2.2.0.0) BUG information: FATAL: Unexpect internal error (setref.c:298) DETAIL: AssertImply failed("!(!var->varattno >= 0) || (var->varattno <= list_length(colNames) + list_length(rte- >pseudocols)))", File: "setrefs.c", Line: 298) HINT: Process 239600 will wait for gp_debug_linger=120 seconds before termination. Note that its locks and other resources will not be released until then. server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. The connection to the server was lost. Attemping reset: Succeeded. I use GDB to debug, the GDB information is the same every time.
