Hi Stas,

For reference, here's a copy of the offending Swank function, minus 

(defun parse-package (string)
     (find-package (let ((*package* *swank-io-package*))
                     (read-from-string string)))))

So are you suggesting that ECL is using knowledge that read-from-string 
returns (values object position) and messing up while compiling?

I wouldn't have guessed that for a good while.

Somehow, re-evaluating this defun after swank has loaded was 
sufficient to clear the problem.  This probably works because it 
activates the interpreter instead of the compiler...

Anyway, this Slime bug appears in ECL commit c0b235, dated 2013-10-10.

Checking out head (237af2) and a previous version of 
src/cmp/cmptype-arith.lsp appears to fix the problem.
