I certainly did not mean to offend or demean anyone or their work. I think what I said is true, in some sense - that particular function was broken in certain versions. I sing Corinna's praises all the time, and greatly value all the volunteer work here! (Sometimes manage to help a little myself.) What I was pointing to was that the issue was not in the OP's program or gcc's compilation or optimization thereof, but that the issue was in the (compiled version of the) mod function itself ... This helps indicate who might be able to diagnose and fix it ... Regards - EM
