Description Erlend Angelsen 2016-02-19 20:59:27 UTC
I'm experiencing random crashes when debugging on device.
It's always related to serializing / deserializing objects from a local cache using Akavache.
The stack trace varies somewhat from crash to crash.
The "Assertion: should not be reached" shows on every 10th crash or so.

Comment 1 Sebastien Pouliot 2016-02-19 22:29:17 UTC
Could you attach the symbolicated crash reports, test case (to reproduce) and all version informations* ? Thanks

*The easiest way to get exact version information is to use the "Xamarin Studio" menu, "About Xamarin Studio" item, "Show Details" button and copy/paste the version informations (you can use the "Copy Information" button).
Comment 2 Sebastien Pouliot 2016-04-12 17:48:41 UTC
We have not received further information and will assume this is not an issue anymore. If you can still affected by this please re-open the bug and include the requested information. Thanks.
