<div>Hi Henrik</div>
<div> </div>
<div>You may recall, a while ago I posted a question to the list about "passive tests" no longer working.</div>
<div>See thread from here <a href="http://www.hswn.dk/hobbiton/2008/10/msg00150.html"><font color="#0000FF"><u>http://www.hswn.dk/hobbiton/2008/10/msg00150.html</u></font></a></div>
<div>Since then, it has happened a few times, but in all cases we have not had a chance to sit down and examine the core.</div>
<div>Until Now.</div>
<div> </div>
<div>Below are our 5 most recent cores. </div>
<div>And the corresponding entry in the bb-network.log file where available. (Not all generate the entry in the log file)</div>
<div> </div>
<div>Colin, our Linux man, and part-time C hacker, had this to say</div>
<div> </div>
<div>---snip---</div>

<div>This GDB was configured as "x86_64-redhat-linux-gnu"...Using host libthread_db library "/lib64/libthread_db.so.1".</div>
<div> </div>
<div>(gdb) l *0x42493a</div>
<div>0x42493a is in ares_free_hostent (ares_free_hostent.c:35).</div>
<div>30 free(host->h_name);</div>
<div>31 for (p = host->h_aliases; *p; p++)</div>
<div>32 free(*p);</div>
<div>33 free(host->h_aliases);</div>
<div>34 free(host->h_addr_list[0]);</div>
<div>35 free(host->h_addr_list);</div>
<div>36 free(host);</div>
<div>37 }</div>
<div>(gdb)</div>
<div> </div>
<div> </div>
<div>line 31: Make 'p' equal to the memory address of host->h_aliases, check that pointer p is not null and increment p</div>
<div>line 32: free the memory pointed at by 'p'</div>
<div> </div>
<div>The problem here is that you check p then free p++. My C is quite rusty but I'd hazard a guess and say line 31 should read like:</div>
<div>31 for (p = host->h_aliases; *(p++);)</div>
<div> </div>
<div>You need to be checking the addess you're going to free, not the one next to it.</div>
<div> </div>
<div>Hope this a) makes sense and b) is vaguely accurate…</div>
<div> </div>
<div>---snip---</div>
<div> </div>
<div>I am no C expert, but looking at the grep output below, it does look like a memory issue.</div>
<div> </div>
<div>Cheers</div>
