<p>Okay thanks. I haven't used docker before (although a huge fan of linux namespaces). I'm assuming I need to do a lot of downloading to get this going? I'm not currently on a good internet connection, and I'm stuck on a very old laptop after leaving my good one on the top of my car and getting on the highway. Is there anything about this docker image that expires?</p><div><div class="h5">

<div>I made a Docker image that you may use to (hopefully) quickly reproduce the bug. The instructions on how to use it are here:</div>

<div><a href="https://github.com/awesomebytes/colm_docker" target="_blank">https://github.com/<wbr>awesomebytes/colm_docker</a></div>
<div> </div>
<div>Mainly:</div>
<div> </div>
<div>docker pull awesomebytes/colm_environment:<wbr>1</div>
<div> </div>
<div>docker run --privileged -v $HOME:/shared -it awesomebytes/colm_environment:<wbr>1</div>

<div>
<div>./COLM-start</div>
<div> </div>
<div> </div>
<div>su - abuild</div>

<div>cd ~/rpmbuild/BUILD/colm-0.13.0.5</div>

<div>I've seen that you had some conversation about that already at:</div>
<div> </div>
<div><a href="http://www.colm.net/pipermail/colm-users/2017-June/000175.html" target="_blank">http://www.colm.net/pipermail/<wbr>colm-users/2017-June/000175.<wbr>html</a></div>
<div> </div>
<div>But it never got anywhere, I think. The last comment of Adrian Thurston says that build dependencies are missing.</div>
<div> </div>
<div>I tried reproducing the same thing and it did work for me (so I got the same compilation error). I did miss the first time doing:</div>
<div> </div>
su - abuild<br><br><br>As explained in <a href="http://www.colm.net/pipermail/colm-users/2017-June/000175.html" target="_blank">http://www.colm.net/pipermail/<wbr>colm-users/2017-June/000175.<wbr>html</a> by Jan Engelhardt.
<div> </div>
<div>Which gave me the same errors mentioned by Adrian.</div>
<div> </div>
<div>So, to reproduce it I did (just for clarity):</div>
<div> </div>
<div>cd tmp</div>
<div>wget <a href="http://inai.de/files/colm/COLM-img" target="_blank">http://inai.de/files/<wbr>colm/COLM-img</a></div>
<div>wget <a href="http://inai.de/files/colm/COLM-initrd" target="_blank">http://inai.de/files/<wbr>colm/COLM-initrd</a><br>
<div>wget <a href="http://inai.de/files/colm/COLM-kernel" target="_blank">http://inai.de/files/<wbr>colm/COLM-kernel</a></div>
<div>wget <a href="http://inai.de/files/colm/COLM-start" target="_blank">http://inai.de/files/colm/<wbr>COLM-start</a><br clear="all">
<div> </div>
<div>chmod +x COLM-start</div>
<div>./COLM-start</div>
<div> </div>
<div>su - abuild</div>
<div> </div>
<div>cd ~/rpmbuild/BUILD/colm-0.13.<wbr>0.5</div>
<div>make clean</div>
<div>./configure</div>
<div>make</div>
<div> </div>
<div> </div>
<div>And I got back to:</div>
<div> </div>
<div>bootstrap1: tree.c:953: colm_tree_downref: Assertion `tree->refs > 0' failed.</div>
<div> </div>
<div> </div>
<div>(I have a VM where I can reproduce it also, but I can't share it publicly).</div>
