This seems correct to me.

While fixing this maybe use MemoryContextAllocZero() instead of subsequent MemSet()?

But this might unroll loop of unnecessary beautifications like DynaHashAlloc() calling
Assert(MemoryContextIsValid(CurrentDynaHashCxt))just before MemoryContextAllocExtended() will repeat same exercise.
