Hi,
If slime-net-coding-system is utf-8-unix, emacs will enter backtrace buffer after cmucl startup. Here is my operation:
1. (setq slime-net-coding-system 'utf-8-unix) 2. C-u M-x slime 3. input "lisp -noinit" 4. cmucl starting... 5. cmucl started, but raises emacs debugger
This error doesn't occur every time. If everything is ok, please quit cmucl then restart it, the error should occur now.
FWIW, I can reproduce this. I don't have such problems with cmucl and xemacs, though. I don't what the cause is, but a backtrace would be useful.
