I assume that nobody else but Don Knuth can fix the bug.

But how can this happen?  I can't imagine that page numbers in index
entries are hard coded.

If you you are keen to investigate further, you'll find the sources of
The TeXbook and the underlying macro package on CTAN.

  http://ctan.org/systems/knuth/dist/tex/texbook.tex
  http://ctan.org/macros/plain/base/manmac.tex


I just notice that manmac.tex appears thrice on CTAN.

  macros/plain/base/manmac.tex
  macros/plain/contrib/samples/manmac.tex
  systems/knuth/dist/lib/manmac.tex

Hopefully all these files are identical or are links to one and the
same file, at least.

Regards,
  Reinhard
