Lpc2000

Hi Robert

OK - you were right. It was working on the Windows PC because the 
module is really getting its memory from heap and uses a pointer. 
The other declaration (static array) was also working but only by 
chance since it was setting and collecting from a 'free' location.

I realised that the target build (testing a new module) was using a 
previous base still with static arrays and so the new module was 
failing.

At least I had the change to get my head around and now it's clear.
