Voodoo screenshot

I have a Coordinate class that contains a Latitude and Longitide as double properties.

Please see the screenshot.

In the first attachment I am inspecting an instance of the class. You can make some interesting observations.
- I know for a fact that LatitideDecimal~=43.55
- The Watch confirms this (the watch is set to "value.LatitudeDecimal"
- The EE is showing LatitudeDecimal==-4214944056E-07 (a very small number)
- When the EE executes value.ToString() you can see it shows teh value as a very large number.

It appears that the in-memory instance of the values contained in the class is corrupt.

Sample project

So this is interesting. Here is a project that replicates the problem.
When debugged in the emulator, the correct values are shown.
When debugged on a physical device, it shows the crazy values.

Zoltan: didn't you already fix this? Does M4A just need to update its Mono runtime?

There were problems with floaring point values in the debugger, those were fixed in c91fc1d6b68994c0c179c4ad99f1a656b14c61ec on mobile master. I don't know which m4a versions include that fix.

Looks like a dup of Bug #8779. Please try using the 4.4.x release.
