Done!

The latest version I could find, cloned from mercurial[0] just minutes ago, does not crash. Well it did once, but not with a segfault, when I encountered an error. I'll keep monitoring it, but it's much better than before.

The output from <newly-compiled executable> --version is

I didn't pass any special flags or anything, simply installed the dependencies they recommend in step 2 of [1] and proceeded as instructed there.
