Well, these make it clear that you've got some pretty big chunks of nonstandard code in the backend, so my first thought is that there's a memory-clobber bug somewhere in that. It might be worth trying to run the code with a debugging malloc library (ElectricFence or some such) to try to locate the culprit. regards, tom lane
