Hi, I'm using CMUCL 19c and Slime from CVS. I get this strange behaviour when I debug a lisp program: -- When I compile and load my files with the following: (dolist (i *source-files*) (declaim (optimize (speed 0) (space 0) (safety 3) (debug 3))) (compile-file (concatenate 'string i ".lisp"))) (dolist (i *source-files*) (declaim (optimize (speed 0) (space 0) (safety 3) (debug 3))) (load (concatenate 'string i ".x86f"))) I can use the 'v' command of the slime-debugger to see my source code, but I lose information for local variables -- When I just load the files using the following: (dolist (i *source-files*) (declaim (optimize (speed 0) (space 0) (safety 3) (debug 3))) (load (concatenate 'string i ".lisp"))) I have information for local variables, but the 'v' command of the debugger does not jump to the source code. Instead, it presents me with some representation of the code which I believe that is the interpreted one, and is much more difficult to use. Is there something that I'm doing wrong, or is it a limitation of slime? thank you very much Giorgos
