It was 0, so no error.

Values in decimal notation:

thread_stacks[count]: 12320
thread_stacks[count][0]: 0
thread_stacks[count][THREAD_STACK_SIZE - 1]: 0 (for thread with no. 0)
thread_stacks[count][THREAD_STACK_SIZE - 2]: 0

It's simply the head of the function.
addr2line gives me line 27 of examples/libedft-example/main.c, so it's
the opening bracket of the thread function:
