Externalthreadhandler was not handling its own stack correctly. It incorrectly referred to the saved LR slot (uninitialized, it turned out) as holding the return value from the called function. Externalthreadhandler is used to call two different functions: profileloop1 and ctrlhandler1. Profileloop1 does not return, so no harm done. Ctrlhandler1 returns a boolean indicating whether the handler took care of the control event (if true, no other handlers run). It's hard to say exactly what uninitialized values are likely to have been returned instead of ctrlhandler1's result, but it probably wasn't helping matters.
