OK, so I spent yesterday learning more about git-bisect and doing
multiple emacs builds from git that I ever expected to, and I'm not sure
I got somewhere.

git-bisect tells me that this commit

    commit 07efb140348b4a4015c69ed102a5fa216978506f

        remove binding_symbol

is the culprit. However, after inspecting it, I confess I am not sure
how. Most likely, I tagged something as bad or good where I shouldn't
have. As the bisecting got me further away from HEAD and into a fairly
deep branch, building cleanly got more and more difficult, and I
couldn't actually replicate the crash anymore.

I will try to replicate this more thoroughly next weekend. I'll need to
come up with a robust way to build so that I can actually automate the
bisecting with `run'.
