--- Comment #5 from tommapson at gmx dot de ---
The problem can be reproduced on Debian 9 using the realtime kernel shipped by
Debian:

$ uname -a
Linux myhost 4.9.0-3-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.30-2+deb9u2
(2017-06-26) x86_64 GNU/Linux

$ gcc --version
gcc (Debian 6.3.0-18) 6.3.0 20170516



When booting the non-rt-kernel 4.9.0-3-amd64, the problem disappears - using
the same binary of main.

As described initially: Without -fsanitize=address the problem is gone, too.
