[ESS-bugs] ESS(SAS), -nw/fontlock problems

[Kasper Daniel Hansen]

Problem: Starting SAS mode in an Emacs in non-window mode yields the error 
message
   Wrong type argument: symbolp, ""
(command to test: emacs -nw test.sas). This results in no buffer being 
openend. Repeating the command opens the buffer, but does not enable 
font-lock mode. If I change my .emacs to disable font-lock the error does not 
occur. If I (in a SAS buffer) disables and then enables font-lock-mode, the 
error is repated. 

Platform:
GNU Emacs 21.2.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 
2002-08-29 on astest
Using Ess-5.2.0beta2

History: A couple of months ago I discovered a font-lock problem when running 
Emacs in -nw mode (or through a terminal), using Ess-5.1.24. This was 
communicated to AJ. Rossini who found a bug in the font-lock definitions of 
the SAS mode. Apparently a fix has been made, because the error message has 
changed from something regarding font-lock variables to the error above. My 
guess is that there is a small error in the bug-fix?
