Hi all, I'm new to SLIME, although a co-worker has been prodding me to look at it for a year. I'm also new to SBCL, although I used CMUCL a fair amount several years ago. I apologize if the following is a FAQ -- I scoured the manual and searched through the gmane archives of this list, but I could've missed something. When I write a core image out from SBCL which I'm talking to via SLIME, then try to load it from the command line without SLIME, I get a long stream of warning messages. This happens immediately on startup. I've deleted my .sbclrc file so user init is not to blame. (Also, when I start up SBCL from the shell, this doesn't happen.) The lisp is not dead, just injured; I can get out of the break loop. However, any time I get back into a break loop, I'm in trouble again. My co-worker suggested setting *debugger-hook* to nil, so I tried that, to no avail. I still get the errors (example below), and once I get back to a usable prompt in the lisp, I see that it's set to SWANK:SWANK-DEBUGGER-HOOK again. I've copied the first chunk of what I see on startup to the end of this message. This is MacOSX, SLIME from CVS a day or two ago, SBCL 1.0.23. Any advice?
