I'm somewhat suprised, since calloc() normally doesn't know if it's getting fresh memory (guaranteed to be zero) or reusing available memory. Perhaps calloc() on your platform knows when it's expanding the C-heap and therefore avoids the redundant clear. > I think I only have a gig of swap on this development machine You should be able to change that with yast or its equivalent. > I still can't find any documentation about a 2GB contiguous allocation > limit for Linux anywhere. I don't know that there is one. Most of the contiguity problems are with Windows, due to its scattering of DLLs in the user process space. There should be tools available for Linux (there are for Windows) to show what's allocated where in your process space. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
