This COMPILE operation should have no effect (assuming *evaluator-mode* = :interpret).
Its effect should not be to crash. However the defaulting form for COMPILE's second argument is (or (macro-function name) (fdefinition name)) where macro-function is only defined on symbols.

* (defun (setf trythis) (new sym) (setf (get sym :something) new))
* (compile '(setf trythis))
