Hi guys,

Take a look at the code sample in the linked article, when debugging on a real device and checking the double values stored in the dictionary it shows apparently random values.

I just tried this, and it worked fine for me both on device and simulator in my test app.

Something is obviously wrong, but it doesn't seem to be that straight-forward, so can you add a test project where this happens? Maybe it's something in the project settings that provokes it.

Looks like from the thread that it only has odd values in the Immediate window?

Might be iPhone4 specific, jawbrey pointed pit it looked like this:
but that was only tested with 2 iPads, the above report was on an iPhone4 too. I'll put together a small app tonight to replicate but would suggest just trying it on an iPhone4 if you have 1 available.

From this StackOverflow post it looks like it might be a bug in returning doubles from method invocations in the debugger:

It does look like a dup, let's consolidate info in one report.
