[climacs-devel] M-q seems broken...

[Eric Moncrieff]

Hi Climacs Developers,

Today I decided I'd check out where Climacs was at.  I downloaded the
latest CVS sources for it and McCLIM, and loaded them up as per the
document, under a recent CVS SBCL.  I started typing, then decided to
reflow a paragraph using M-q.  And climacs crashed, bringing up the
following backtrace in slime:

There is no applicable method for the generic function
  #<STANDARD-GENERIC-FUNCTION CLIMACS-SYNTAX:BEGINNING-OF-PARAGRAPH (1)>
when called with arguments
  (#<CLIMACS-BUFFER:STANDARD-RIGHT-STICKY-MARK {CAE2BB1}>
   #<CLIMACS-SYNTAX:BASIC-SYNTAX {C96C239}>).
   [Condition of type SIMPLE-ERROR]

Restarts:
  0: [ABORT] Abort handling SLIME request.
  1: [DESTROY-THREAD] Destroy this thread (22501)

Perhaps this has something to do with the recent buffer implementation
changes?

Procedure to reproduce:

(climacs-gui::climacs)

;; in new climacs window

foo bar M-q

Let me know if there's any more information you need.

Thanks!
Eric
