<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Ali.<br>
<br>
This is perhaps not a clear case since it involves dune and its use on mac<br>
but since the code you are using is from dune-fem it would be good<br>
to keep these mail on the dune-fem list<br>
(http://lists.dune-project.org/mailman/listinfo/dune-fem)<br>
<br>
Did I understand correctly: the code ran successfully producing the<br>
right results but terminated with the segfaults you have shown in your mail?<br>
Perhaps we can reproduce the problem (seems to be dune+alu) with<br>
some other program:<br>
could you install the dune-grid-howto and use one of the test programs there<br>
with alu to see if the same segfaults occurs. <br>
Perhaps the intergration.cc testcase?<br>
<br>
Thanks<br>
Andreas<br>

<div>Hi, I recently attended the DUNE School at the University of Warwick and have since been trying to get DUNE running under Mac OS X so that I can develop some code.</div>
<div><br>
</div>
<div>I have managed to get Dune installed and am able to compile the example code we were given at the DUNE school, but they all exit with a segmentation fault after finishing the execution of main(), e.g.</div>

<div>I've also been able to run the code in Xcode in order to debug it but the best I can do is find where the error is occurring:</div>
