I suspect, going by all 3 failing animals being 32-bit which have a MAXIMUM_ALIGNOF 8 and SIZEOF_SIZE_T of 4 that this is due to the lack of padding in the MemoryChunk struct. AllocChunkData and GenerationChunk had padding to account for sizeof(Size) being 4 and sizeof(void *) being 8, I didn't add that to MemoryChunk, so I'll do that now. David
