It looks that tupDesc contains invalid pointer. I found some strange
assignment in ExecAssignScanTypeFromOuterPlan function. See comment
bellow. OuterPlanState expects PlaneState structure instead ScanState.
00762 ExecAssignScanTypeFromOuterPlan(ScanState *scanstate)
00763 {
00764 PlanState *outerPlan;
00765 TupleDesc tupDesc;
00766
00767 outerPlan = outerPlanState(scanstate); ^^^^^ scanstate->ps ??
00768 tupDesc = ExecGetResultType(outerPlan);
00769
00770 ExecAssignScanType(scanstate, tupDesc);
00771 }
