[slime-devel] slime bug: Caught error when trying to extend the region for fontification

[David Reitter]

Emacs version is Aquamacs/Cocoa, development build (dr/dev branch),  
based on current Emacs 23 in development (which is probably sufficient  
to reproduce).
This occurred during redisplay, more precisely when scrolling down  
with the mouse scroll wheel.  (window-start) after the scroll action  
is 6150.

SLIME is some recent CVS build.

lispdoc.lisp is attached.



Warning (slime): "lispdoc.lisp":166:0 (pt=6683).
Caught error when trying to extend the region for fontification.
The error was: (error "Invalid search bound (wrong side of point)")
Further: font-lock-beg=7694, font-lock-end=8223.

This is a bug in Slime itself. Please report this to the
mailinglist slime-devel at common-lisp.net and include your Emacs
version, the guilty Lisp source file, the header of this
message, and the following backtrace.
