Android app crashes after successfully executing all desired actions

I'm developing with RAD-Studio XE7 an app for Android. Everything is going fine up to the point where the app crashes with seg-fault(11). I retraced this to the "end;" of a procedure, where the system-memory-releases are executed. In System._InstClear the program stops at "ldr.w r1 [r1,#-60]" where the register R1 is 0.

• Hardware: Sony Xperia Z2 Tablet (SGP511)
• Android: 4.4.2
• Kernel: 3.4.0-perf-g46a79a0

It has both NEON and ArmV7.

Compiling and running as an .exe works flawless.

I'm using runtime-created Indy-TCPComponents. Maybe this could cause issues.

If some useful information is missing, I would be delighted to provide it.

Edit: Logcat output added

The log indicates that the application is not responding anymore for several (> 5) seconds:

I/InputDispatcher( 966): Application is not responding: AppWindowToken{447e94b0 token=Token{44808ad0 ActivityRecord{44bc8ea0 u0 com.android.systemui/.recent.RecentsActivity t269}}} - Window{44fdfe90 u0 com.embarcadero.Project1/com.embarcadero.firemonkey.FMXNativeActivity}. It has been 5007.3ms since event, 5005.6ms s ince wait started. Reason: Waiting because the focused window has not finished processing the input events that were previously delivered to it.

And then

W/InputDispatcher( 966): Asynchronous input event injection timed out.

So it seems that after all the successful execution of desired actions, the application stops to respond to input.

Does the app use threads (maybe indirectly, in Indy components) without terminating and freeing them properly?

Can you reduce the application to a minimum which shows the error?
