Application crashes on fast resume in WP8

Any app built for Windows Phone 8 crashes intermittently leaving and returning to eh application (fast resume/fast app switching). Steps to reproduce:

1. Launch the app
2. Press the hardware windows key
3. Press the hardware back key
4. Repeat

Sometimes everything works fine but a lot of the time the app crashes within 10 tries or so. This happens both in our proper app but also in a completely "clean" project without any plug-ins which only displays a cube and nothing else which makes me thing it has to be a general Unity (or Visual Studio) problem:

Been able to reproduce the issue both on physical Lumia 520 devices as well as when debugging in Visual Studio using the "8.1 WVGA 4 inch 512" emulator.

When the app crashes one of the following errors are displayed in the log:
The program '[4052] TaskHost.exe' has exited with code -1073741816 (0xc0000008) 'An invalid handle was specified'.
The program '[2856] TaskHost.exe' has exited with code -1073741819 (0xc0000005) 'Access violation'.
The program '[3508] TaskHost.exe' has exited with code -1073740940 (0xc0000374).

Anyone experienced anything similar or have any advice what might cause this?

 

Hello Turbolsland,

I have been experiencing the same issue with my game. Have you found any solution to this issue.
Or have you been able to trace the source for this issue ?
