Congratulations, it's another compiler bug.

On Windows 32 bit this code behaves in another way, it doesn't crash:

import std.stdio;
void main() {
    for (idouble j = -2i; j <= 2i; j += 0.125i) {
        for (double r = -2; r <= 2; r += 0.0625) {
            cdouble c = r + j;
            writeln(c.re, " ", c.im);
        }
    }
}


Without -O:
-2 -2
-1.9375 -2
-1.875 -2
-1.8125 -2
-1.75 -2
...
1.75 2
1.8125 2
1.875 2
1.9375 2
2 2


With -O:
-0 -9.88131e-324
-0 -9.88131e-324
-0 -9.88131e-324
-0 -9.88131e-324
-0 -9.88131e-324
-0 -9.88131e-324
-0 -9.88131e-324
...
