I put the Emacs cursor after the last right-paren, issued C-c C-c, and the SLIME debugger popped up; it said (I've expanded the top stack frame):
I experienced the same with the slime-1.0 tarball. But for AllegroCL. It says it got 4 args, expecting 3. (Cannot post the backtrace, since I installed it on a different machine.)
It has probably something to do with the attempt to eliminate the redefinition warnings when C-c C-c'ing. Maybe an incomplete commit? (Sorry, I haven't checked the latest Slime from CVS, since my current Slime works quite well and I currently don't have the time to work on it.)
