Subject: Bug in buffer-local-value
Date: Thu, 26 May 2005 22:13:18 -0500 (CDT)	[thread overview]
Message-ID: <200505270313.j4R3DIQ05157@raven.dms.auburn.edu> (raw)

There is a bug in buffer-local-value, when used in connection with
defvaralias.  I believe that the ielm run below is self-explanatory.
The bug affects `C-h v" in a very confusing way.  I am insufficiently
familiar with the involved C code to fix this myself.
