Hello there.
I am new to this forum and it seems very good.

I was programming in C with Windows and I need a 2d-array with 800x800 entries.
It doesn't seem very big, but... when I run the program, it fails.

Code:
int main() {
	int M[800][800];
	return 0;
}
In Linux all works well. Any tips?

Regards,
Ian Liu.
