I had a peek at the icc manual. For icc, -g by itself implies -O0 and -fno-omit-frame-pointer, so it will be slower. However, -g -O2 -fomit-frame-pointer shouldn't be any slower than without the -g. For gcc, -g does what you said. -- |>|\/|< /--------------------------------------------------------------------------\ |David M.
