--- Comment #2 from Chris Johns <chris at contemporary dot net.au> --- Thanks for the quick response. The clean trap instruction did confuse me. I suppose my work around to move the code into another file stops gcc detecting the access. Is this true ? I am happy to build our code with the check enabled because accessing 0 is something we trap for with MMU targets such as ARM and PowerPC.
