Author: wmb Date: 2007-08-24 01:31:44 +0200 (Fri, 24 Aug 2007) New Revision: 576 Modified: forth/kernel/kernel.fth Log: Fixed a longstanding bug that caused misleading error messages when interpreting from files. The problem is that the line buffer memory has been freed and possibly overwritten before the undefined word name is displayed. The solution is to copy the word name to a dedicated buffer.
