Look at this code:
import std.stdio;
class Foo {
int value = 123456;
}
struct Bar {
this(Foo f) { foo = f; }
@property auto lambda() {
return (){ writefln("value = %s", foo.value); };
}
Foo foo;
}
auto getLambda(Foo f) {
return Bar(f).lambda; // lambda closure points to temporary
Bar on the stack
}
void main() {
Foo foo = new Foo;
auto lambda = getLambda(foo);
lambda(); // undefined behaviour? prints some number, but not
123456
}
It compiles, but result is unpredictable.
Platform: Windows 7, dmd 2.062
For reproducing this behaviour it's necessary to omit -inline and
-O flags, try simple "rdmd test.d"
