This commit seems to be causing an LLDB crash. I'm still working on gathering
info and reducing it, but maybe the crash reason is obvious to you given this
stack trace:

The class definition for the expression being evaluated can be found here:

(It crashes in the same-ish w/o assertions too; this is just the more helpful
stack trace :) )
