The app I'm developing has undergone some semi-major changes recently.
At some point, I seem to have introduced code that produces either Fatal Signal 11, Fatal Signal 7, or no error at all when you try to exit the app.
Before exiting the app, I use Activity_KeyPress to check if the user really wants to quit. If so, the function returns false.
In that case, I'd expect the program to continue in Activity_Pause, which doesn't happen. The program just exits without going there.
If the fatal signal occures, it does so directly after processing the return line from Activity_KeyPress.
The Log file for Fatal Signal 11 looks like this:
I've been trying to figure out the problem for a few hours now, but didn't find a solution.
Also, it seems to only appear on one of my three testing phones, a HTC One.
Do you have any ideas on what could be the cause?

Do you have any ideas on what could be the cause?
