You have not discovered a bug in LaTeX. The \verb command does not
work properly when used within the argument of another command (here
compounded: \put and \makebox).  See p66 of Lamport's book:

"A verbatim environment or \verb command may not appear within an
argument of any other command.  (However, they may appear inside
another environment.)"

Michael Downes posted here within the last 48 hours a very nice solution
to the problem of setting the underscore character within computer voice,
(q.v.).

BTW, you really _can_ put a \verb command in the argument of another
command, but the argument of the \verb command had better not contain
any specially catcoded characters!

Cheers,
Art
