Forget about the stack - move them to the heap - thats what the heap is for.

People, advice you to do right thing - to allocate large memory arrays dynamically, i.e. on the heap. But you can enlarge stack size if you want.

Solution 1

That's because you are now attempting to allocate about 80 MB of the program stack.
