[Pgpool-hackers] 3.0 Segfault when processing front-end response CLOSE

[Dustin Land]

I recently upgraded to 3.0 and ran into the following issue...

Program terminated with signal 11, Segmentation fault.
#0  Close (frontend=<value optimized out>, backend=<value optimized out>, len=5, contents=0xebdbe0 "PC_4") at pool_proto_modules.c:1017


It looks like pstmt never gets set on "*contents == 'P'" calls; so attempts to "query_context = pstmt->qctxt" fail.  Adding the following patch helped me get past the issue.  

# diff -c pool_proto_modules.c pool_proto_modules.c.patch

                }

                session_context->pending_portal = portal;
+                 pstmt = portal->pstmt;
        }
        else
        {
