bug in (error "testing")

[Richard M. Heiberger]

There is a bug in the (error) function in NTemacs 21.1.90 as compared
to 20.7.

In both cases I am using the precompiled versions with
   emacs -q --no-site-file
and enter the command
  (error "testing") C-j
in the *scratch* buffer

20.7:  the echo line and *Messages* buffer display the word "testing"

21.1.90: nothing is displayed in the echo line or *Messages*.
The *Backtrace* appears.  *Messages* says "Entering debugger..."

thanks
Rich
