Hi, my partner (Tale) and I are computer science students at the University of Michigan. We're in an advanced software engineering course (EECS 481), and our final project is to contribute to an open-source project.

This community-tagged bug looks like a great C++ task for us to work on. We have successfully built the master branch locally on our Macs.

Is anyone else actively working on this? If not, we'd love to try and submit a fix over the next few weeks."
