However, Vincent keeps saying it produces bad code that doesn't work. I think he just writes bad code himself and then complains when the compiler does something that is unexpected, even if it is legal. I use the intel compiler everywhere, including my cluster where several have carefully compared program output between intel and gcc to check for correctness. Intel is faster and correct, which is all I want. :)
