Hi guys,

I've been looking through the memory management system today.

When a request is made for a memory memory chunk larger than
ALLOC_CHUNK_LIMIT, AllocSetAlloc() uses malloc() to give the request its
own block. The result is tested by AllocSetAlloc() to see if the memory
was allocated.

Irrespective of this, a chunk can be returned which has not had memory
allocated to it. There is no testing of the return status of
palloc() through out the code. 

Was/has this been addressed?

Thanks

Gavin
