</span>Definitely try to compile with debugging, then run in gdb. This should at<br>
least give you a better idea which part of the code is involved, and<br>
possibly which library.<br>
<br>
Problems are often caused by incompatible libraries, especially if there<br>
are several versions of a library present in the system.<br>
