My SBCL 0.8.6.13 goes into an endless loop or something when I enter:
(compile nil '(lambda nil (defparameter *truth-table* ...)))
Can someone confirm this?
I think probably "or something", but yes, SBCL's behaviour here seems supremely suboptimal.
What's actually happening is that it's converting the call to VECTOR into (let ((array (make-array <largenum>))) (setf (svref array 0) 191) (setf (svref array 1) 191) ... ... <largenum times> ...) and this is causing the compiler to spend a lot of time optimizing and reoptimizing the body. It does eventually finish and give the right answer, though.
Could this be reported as an sbcl bug, please?
Cheers,
Christophe
