C-like static array size inference - how?

Hello. I am working on a project related to low-level development as a beginner, and i decided to pick D as the most optimal programming language for that, in large part because of it's strong integration with C and C++. I happen to have a lot of arrays that i want to translate to D,

Static array size?

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.

simendsjo: Why is this a bug? Currently it isn't. But I (and few other people) have asked for it to be a bug, because it sometimes leads to not catching a programmer mistake. Static means it's only one instance (per thread), right? The compiler cannot know if you meant to fill the entire

Yeah, I don't have a lot of votes left, in fact I only have one left. :s I think we're basically on our own when it comes to these kinds of issues. We'll either get a compiler with a better warning system (maybe GDC.. DDMD in the future), or we'll make some kind of Lint tool for D. The latter
