<p class="MsoNormal">just from a quick look at this code, my guess is that you should not be using stack addresses in your list.<o:p></o:p></p>
<p class="MsoNormal">Your local_head is on the stack, therefore it gets corrupted after you exit your function and invoke other functions.<o:p></o:p></p>
<p class="MsoNormal">Did you really mean to store a pointer to local_head, or was your intention to point to the first element on local_head?<o:p></o:p></p>
