I assume your program looks like:
	main()
	{	float a[5000]; float b[5000]; float c[5000]; float d[5000];
		...
	}
A bit of multiplication gives us 80,000 bytes you are trying to allocate
on the stack. The PC hardware only allows a 64k byte stack, MSC allows
something less than that.

You'll need to allocate arrays that large statically, or use malloc() to
dynamically generate storage for them.
