bugs?

[xwang@ctr.columbia.edu (Xin Wang)]

I am a nsv2 user and I am trying to do some routing simulation on top of the 
simulator. I downloaded the draft version of PIM-SM based on nsv2 
written by Ahmed from USC. When I tried to test the simulator 
after compiling it, I got some exception errors. I remembered there were
the similar errors the first time I downloaded nsv2 itself. The bug was fixed 
afterwards. I think the bugs for the PIM-SM is due to the author
using the old version of nsv2. Anyone knows what the possible bugs for 
this? And if there exists any debugging tool for OTcl? Thanks a lot.
