Hmm, works for me on today's HEAD.

There are two Assert(false) in that file, neither of them particularly
close to line 2833 as of today, so I'm not sure what version you are
using or which one you're hitting.  Nonetheless, I'll go out on a
limb and guess that this will go away if you do "git clean -dfxq"
and a full rebuild.  It smells like different files getting out of
sync about the representation of ExprEvalOp or ExprEvalStep.
