Re: [ns] segmentation fault (fwd)

I presume by 'changing ns_tcl' you mean you've changed some scripts under
tcl/ then recompile. gen/ns_tcl.cc is automatically generated and should
not be manually editted.

If I were you I'd look at the way your bound variable is initialized and
where it is first accessed. Seems like during ns initialization some of
your bound variable was accessed incorrectly. If you are still not sure,
build a debugging version of tclcl (make clean then change -O2 in Makefile
to -g), link it against ns, set a breakpoint in InstVarReal::set() or
TracedDouble::assign() (tracedvar.{h,cc}) and see what's going on.
