I did try the patch. It fails just the same way.
With or without the patch, with both 8.2 and 8.3, the 0xffffff00
gets passed from seg_same end ends up atleast in ExecutePlan():
ExecutePlan (estate=0xc1c468, planstate=0xc1c698, operation=CMD_SELECT,
numberTuples=0, direction=ForwardScanDirection, dest=0xc03250)
at execMain.c:1239
1239 if (TupIsNull(planSlot))
(gdb) p /x planSlot->tts_values[0]
$4 = 0xffffff00

a true, 8.3 into a false.
