>
> In function AdvanceMemoryAccountingGeneration, we first assign
> "RolloverMemoryAccount->peak = Max(RolloverMemoryAccount->peak,
> MemoryAccountingPeakBalance);", then we call elog if there is a generation
> overflow. Then we assert "Assert(RolloverMemoryAccount->peak >=
> MemoryAccountingPeakBalance);".
> If elog allocates additional memory, then this causes the assertion to fail.
