(defstruct foo (x 0 :type (unsigned-byte 64)))
(make-foo :x 4177526783)

> Error: The value 4177526783 is not of the expected type (UNSIGNED-BYTE 64).

This is compiling a fixnum test into the (incf y inc) for some reason.

? (defun test () (symbol-macrolet ((inc 0.5)) (loop with y = 0 do (incf y inc) while (< y 100))))
TEST
? (test)
> Error: value 0.5 is not of the expected type FIXNUM.
> While executing: TEST, in process listener(1).
> Type :POP to abort, :R for a list of available restarts.
> Type :? for other options.

If a compare-and-swap (cmpxchgq) instruction used in the subprimitive _SPstore_node_conditional failed (cleard the z flag), the subsequent branch instruction branched forward to local label 0. It should have branched backward, retrying the store-conditional.

Branching backward typically caused code in _SPprogvsave - which checks to ensure that a list of values was a proper list - to signal a confusing, spurious error.
