> 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.
