</div>...so nobody can provide any solution.<br>

As explained a diverging number of times, "segmentation fault"<br>
means nothing but "something very wrong happened".<br>
There is NO WAY anybody can say anything sensible about a<br>
"segmentation fault" without additional information.<br>
First and most important piece of information:<br>
* Is the problem reproducible with different compilers /<br>
libraries / op.sys / hardware / input options / examples /<br>
phases of the moon?<br>
