But you have lexical-binding:t set at the top of the file, and
`buffer' is a let-bound variable, whereas `add-to-list' operates on
dynamic variables. Hmm, looking at the disassembly it seems that
add-to-list's compiler macro fixed up the problem, although I thought
it should give a compile warning in this situation.

What about this one:

I don't know why it makes a difference.
