Invalid code puts the compiler into an infinite loop

Bug Description

The following code fragment confuses the compiler:
   (0) ; illegal function call
   (block block1027
     (let ((foo (list (list (lambda () (return-from block1027 2))))))
       (declare (special foo))
       (declare (dynamic-extent foo))
   (go top))

The compiler correctly reports "illegal function call" and then goes into an infinite loop.
SBCL 1.1.13, Linux x86_64.
