Lpc2000

It's unlikely to be a compiler problem with optimisation: I believe 
the ARM compiler to be very reliable in terms of producing correct 
code.

You don't say anything about the exact failure mode.

I'd suggest removing as much as possible to get as small an example 
as possible of the problematic code, and work from there.
