What does ", string s" do here inside the is expression?

http://digitalmars.com/d/2.0/arrays.html says static arrays are
limited to 16mb, but I can only allocate 1mb.
My fault, or bug?
enum size = (16 * 1024 * 1024) / int.sizeof;
//int[size] a; // Error: index 4194304 overflow for static
array
enum size2 = (16 * 1000 * 1000) /
This is using dmd 2.052 on windows by the way.

I think you missed my "/int.sizeof" at the end.
enum size = (16*1024*1024)/int.sizeof;
int[size] a; // "Error index overflow for static" as expected
int[size-1] b; // stack overflow
int[250_001] c; // stack overflow
int[250_000] d; // ok
immutable(int[]) a = [1,2,3];
assert(!is(typeof({a[0] = 0;}))); // cannot change elements
assert(!is(typeof({a = [1,1,1];}))); // cannot rebind
// but I'm allowed to sort in place...
a.reverse;
assert(a == [3,2,1]);

It accepts 4_000_000 ints, but not (16 * 1024 * 1024) / int.sizeof = 4_194_304
ints. I don't know why it's designed this way... I'd like 4_194_304 ints

It's a known bug, already in Bugzilla.

It turns out the receiveTimeout technique didn't work well for me. In
my case, there's a timer which spawns a high-priority thread calling
`foo` several hundred times per second. What I really needed is to
exhaust the message queue, and then do some other work after that. So
I've added a `shared in

I meant with the array as a global variable.
The stack on Windows can be set very large too, with -L/STACK:1000
