That's expected: the default value of standard-display-table is nil.
You should use something like this instead:
(or standard-display-table
(setq standard-display-table (make-display-table)))
> The uncompiled "bug.el" version works fine though.
Probably because you load it into a session that already has
standard-display-table initialized to a non-nil value.
