One thing which might make a difference: try adding "-lpthread" to the
link command. I've occasionally encountered all sorts of odd behaviour
with programs which are linked against libraries which are linked
against libpthread (typically libGL), but where the binary itself
isn't linked directly against libpthread.

Other than that, given that the program is hanging in "pure" Tcl code
(no NVIZ-specific functions in the backtrace), I can only assume that
something in the NVIZ initialisation is breaking Tcl.
