digitalmars.D.learn - Static array size?

reply Suliman <evermind live.ru> writes:
Docs says that:
"The total size of a static array cannot exceed 16Mb."
But when I am creation array of:
int [1000_000] x; // 1000_000 is equal ~ 0,95MB
app crush on start.

Should it's reserve this memory with guaranty? I mean that after 
app start it should take +0.95MB of RAM in task manager.

multiply by 4

Also static array is not on the heap so take care to which column of the task manager you monitor.

First of all it is 4bytes * 1000_000 = 4000_000 bytes = 4kbyte, and it should not crash, are you sure this is the reason why app crash?

First of all, as others said it is 4 bytes * 1000000, what gives about 4MB. Do you allocate this array on the stack? (local variables are created on the stack) If yes, maybe you've exceeded the size of the stack. Declare the array out of the scope of any function and check again. The size of the stack can be set in the linker (http://forum.dlang.org/post/mailman.766.1291253609.21107.digitalmars-d puremagic.com).
