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.


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


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