- Ilya Zaitseff (28/28) Dec 20 2004 Code below outputs '1' instead '0'.
- Simon Buchan (16/45) Dec 20 2004 dmd 0.109 on XP outputs 0. What version do you use?
- Ilya Zaitseff (4/42) Dec 21 2004 Strange, on the other machine there is no such bug.

Code below outputs '1' instead '0'.
'bar' value overrides 'foo' value, when in there are no ctor in class 'B'.
If uncomment B ctor, output is '0', as expected.
<code>
class A
{
this() {}
}
class B: A
{
int foo;
// this() {}
}
class C: B
{
int bar;
this()
{
foo = 0;
bar = 1;
}
}
void main()
{
C c = new C();
printf("%d", c.foo); // 1, expecting 0
}
</code>

Maybe my D installation is broken.I am assusming there would have to be for it to do this... compiler version and environment may help (If they are not identical) Also: this may be somewhat like the eax "return" "behavior" (Its a feature, not a bug! :D), i.e. whatever was in eax is returned from void main(). Unless this always happens with different compilations... or something... -- "Unhappy Microsoft customers have a funny way of becoming Linux, Salesforce.com and Oracle customers." - www.microsoft-watch.com: "The Year in Review: Microsoft Opens Up" -- "I plan on at least one critical patch every month, and I haven't been disappointed." - Adam Hansen, manager of security at Sonnenschein Nath & Rosenthal LLP (Quote from http://www.eweek.com/article2/0,1759,1736104,00.asp) -- "It's been a challenge to "reteach or retrain" Web users to pay for content, said Pizey" -Wired website: "The Incredible Shrinking Comic"
