There are .sah files, in which the data is stored to analyse. So i
deleted these files and the client downloads a new package -> new data

Yes, it did happen that the segfault reoccured and there is nothing in
the dmesg. This was also my first thought, then checked
/var/log/messages with a tail and it stucked. No ctrl-c.

Tried this:

#define _GNU_SOURCE 1
#include <fenv.h>

main() {
double zero=0.0;
double one=1.0;


one /=zero;

...but nothing happens.
