> 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. The
> information is:
> Loaded symbols for /lib64/libnss_files.so.2
> 0x00000032dd40eb5c in recv 0 from /lib64/libpthread.so.0

> the SQL sentence is long, Occupies the entire screen, total 45 lines. the SQL
> sentence contain "nested select", many "union all", "where", "or", "and", and
> also have "group by" and "having".
> I try to "explain this SQL" to get the execution plan, but it report the same
> error, and then can not get the execution plan.
> I also try to "set optimizer=off" and retry the SQL sentence, but the same
> error happen, and "show optimizer" the optimizer is "on" (automatically set
> "on").
