| Mark,
thanks!
i have a simple xcode project that does a malloc that for the latest data set has grown to just under 3gb. the malloc is failing (on 10.3.9). since i have 4gb of ram and the docs imply i can access up to 4gb space without having to go to 64 bit addressing, i was hoping there was something simple i could do to make this work?
There probably isn't anything simple you can do to solve the problem without reworking your code, at least a little. While your process has a 4GB address space, there is bound to be some fragmentation of the available space, so the largest block you can allocate will always be somewhat smaller.
its a simple command line app that merges a set of images of irregular size, which may overlap (i want to keep the last ones). its a quick and dirty tool for some gis work i am doing. i can mod to do in smaller pieces, i just was hoping there was a quicker way.
thanks jim
