ns and otcl crash on specific variable names

[Hongxia.Quan@Dartmouth.EDU (Hongxia Quan)]

Hi, All:

I download the latest version of ns and build it on redhat linux. 
Then I went to otcl directory and started otclsh

bonita:otcl-1.0a4 > otclsh
% Class Bagel
Bagel
% Bagel p
p
% Bagel p1
Segmentation fault

bonita:otcl-1.0a4 >    
               
This looks like otcl does not like variable names p2. Then I started ns.

bonita:otcl-1.0a4 > cd ../ns-2.1b5/
bonita:ns-2.1b5 > ns
% Simulator p2
Segmentation fault

bonita:ns-2.1b5 > ns
% Simulator p
p
% exit

bonita:ns-2.1b5 >


Does anyone know why variable name p2 caused ns and otcl to crash and how to fix it? Any ideas will be appreciated. Thanks.
