On: A C Heisenbug in the wild

[icecommander]

The Python analog would be something like this:

assert (object() < object()) == False

(try running this in the interpreter a few times)

[leot → icecommander]

Not really.

The example given is equivalent in badness to:

  g = Timer()
  assert g.startTimer() == 0

... and then wondering why the timer doesn't start when you run your program in "optimized" mode.

[coconutrandom → icecommander]

Woah... so this is coercing it to a string and the address in hex is being compared. Am I off on this?

[leot → coconutrandom]

Yes. Python is not that mysterious.

For generic objects, the __lt__ and __gt__ methods are simply defined the only way that's sensible, which is effectively as a pointer location comparison.
