I had this problem once before and I can't for the life of me remember what I did to fix it. I just downloaded the latest CVS of slime (todays) and blew away allthe fasls like always. Then I started emacs and when I ran M-x slime I get the following: (load "/home/jcunningham/installed/slime/swank-loader.lisp" :verbose t) (swank:start-server "/tmp/slime.10888" :external-format :iso-latin-1-unix) Error in function UNIX::SIGSEGV-HANDLER: Segmentation Violation at #x100168E8. [Condition of type SIMPLE-ERROR] Restarts: 0: [ABORT] Skip remaining initializations. Debug (type H for help) (UNIX::SIGSEGV-HANDLER #<unused-arg> #<unused-arg> #.(SYSTEM:INT-SAP #x3FFFEC98)) Source: Error finding source: Error in function LISP::%ENUMERATE-SEARCH-LIST: Undefined search list: default 0] I'm running CMUCL 19b and it hasn't changed in awhile. I'm stumped. Does anyone have any ideas? --Jeff
