And, unless you are using that chunk of memory all the time, you shouldn't declare it as a fixed array, anyway. Using a dynamic structure allows for more flexibility in only using the memory needed and allows you to grow the array size, if needed.

Declaring an array with a lot of items always causes a crash.

int main (int argc, const char * argv[]) {
unsigned long notSoBigArray[200000];
return 0;
}

That's only about 780K. Why the crash?

Because you blew your stack in a big way, I expect. Stack space, in
threaded applications, is pretty limited--usually less than 1M, often as
low as 20-40K. (Depends on the platform and all)

For something that size, malloc the memory instead.
