[MIT-Scheme-devel] ,a doesn't work well, tab completion

[Frank]

When any error occurs, after putting ",a", the source code window doesn't resume.

And tab completion doesn't work well.
To MIT-Scheme developer: It might be a bug in MIT-Scheme.

Error occurs

The object nil, passed as an argument to string-ci=?, is not a string.
  [wrong-type-argument]

Restarts:
  0: [abort] Return to SLIME top-level.

Backtrace:
  0: ;undefined _expression_
  1: (if make(not (and (string? string1) (string? string2))) (guarantee-2-strings/fail string1 string2 (quote string-ci=?)))
  2: (if (string? pstring) (string-ci=? *buffer-pstring* "COMMON-LISP-USER") #t)
  3: (pstring->env pstring)
  4: (emacs-rex socket sexp pstring)
