The most likely cause of running out of stack space is you have infinite recursion, i.e., a function calling itself over and over, or arrays.
Check for recursion first, that's what usually causes it, at least on the PC. Arrays also eat up stack space in a hurry. UInt32 oneWhoppingBigArray[1000]; <- This will eat up 2k of stack space! This is much better: MemPtr array = MemPtrNew(1000*sizeof(UInt32)); UInt32* oneWhoppingBigArray = (UInt32*)array; This will allocate the space for the array on the dynamic heap instead of the stack. Just remember to free it when you are done. In this case the only memory used by the stack is the memory to hold the MemPtr and the UInt32 pointer, which is a total of... uh...8 bytes I guess. Much better than 2k. Anytime you pass an argument to a function it is passed on the stack. Anytime you create an object, it is created on the stack. To allocate memory in dynamic memory instead, use MemPtrNew and MemHandle. If you are running out of stack space, increasing the size of the stack is almost certainly not the correct answer. You need to rework your code.
