A small Java program found in a blog post:


class Flow {
    static public void main(String[] args) {
        for (int i = 0; i < 6; ++i) {
            System.out.println("Loop: " + i);

            try {
                try {
                    if (i == 3)
                        break;
                } finally {
                    if (i % 2 != 0)
                        throw new Exception("");
                }
            } catch (Exception e) {
                System.out.println("Caught");
            }
        }
    }
}


Its output:

Loop: 0
Loop: 1
Caught
Loop: 2
Loop: 3
Caught
Loop: 4
Loop: 5
Caught


A D translation:

import std.stdio;

void main() {
    foreach (i; 0 .. 6) {
        writeln("Loop: ", i);

        try {
            try {
                if (i == 3)
                    break;
            } finally {
                if (i % 2 != 0)
                    throw new Exception("");
            }
        } catch (Exception e) {
            writeln("Caught");
        }
    }
}


dmd 2.063beta prints:

Loop: 0
Loop: 1
Caught
Loop: 2
Loop: 3

And then it crashes.

Various people in D.learn and on IRC show that maybe this fails only on 32 bit Windows.
