The most likely bet is that your code wrote past the end of a memory
chunk it had palloc'd, and thereby clobbered the bookkeeping info for
the next physically adjacent chunk.

You could home in on the location of the clobber by sprinkling
"MemoryContextCheck(TopMemoryContext)" calls through your code.
