In that case I suggest you compile with -da and compare the .expand dumps for the optimised and unoptimised code. If they both use the same bad sequence, see (a) which pass manages to optimise it and (b) figure out why the expand-time code is so bad. If the difference is already present at expand time then presumably something is going wrong earlier. Thanks, Richard
