I have TeX Live since 2007.

\tableofcontents does nothing special, it just prints the contents of
the toc file. If LaTeX locks in this command and displays just a part
of the table of contents, the most probable reason is that you have a
fragile macro in your \part, \chapter, \section etc. The macro is the
expanded on a wrong place which can cause an endless loop. Try to
shorten your document (you can put \end{document} to the middle of the
file, the rest will be ignored). Remove the .aux and .toc files and
try to compile the document. You will see where it fails. You can also
look to the aux file and toc file. If you see a strange garbage, you
will know that this it the place where a fragile macro gets expanded.
Having found the place you have to protect the fragile macro with
\protect. If you use the hyperref package, you can get a similar
problem when the outlines are generated. You may need \texorpdfstring.
