Yes, I agree. One point is that some _peripherals_ of the LPC needs a 4
byte alignment. e.g. the IAP (flash programmer rom code) and some other
peripherals like the EMAC too. So I strongly advice to keep at least the
malloc aligned to 4. 

But anyway for now everything seems to be ok. We just should keep this
in mind.

Bye,

Ole
