Description

This bug seems to be quite nasty as I've been able to reproduce it ONLY on a specific device, among the 15 at my hand. On ALL the other devices tested the code works perfectly fine.

It is sufficient to create a new project and run it on the device. If the user puts the application in background (HOME button) and brings it back, the application crashes with an heap corruption.

"org.qtproject.example.TEST" died.

5.5.1 is UNEFFECTED: the code works fine and no crash occurs. I've also noted that context switch between app and OS seems to work smoother on 5.5.1, don't know if that's a symptom or a cause, though.
