Very strange.

Yes, it does.

I'm using version 1.67 (2002)  installed many years ago
on a Mac, via  fink .
I've not tested later versions for Linux or Unix; but with 
such a simple document there should not be any significant difference.
That there seems to be, for you, puzzles me greatly.

Please also add the option   -verbosity 10 
which generates significantly more screen messages.

In particular, you should have a block such as:

>>>  *** End-of-partition ***\documentclass[12pt]<<1>>article<<1>>
>>> \usepackage<<2>>html<<2>>
>>> \usepackage<<3>>verbatim<<3>>
>>> \begin<<4>>document<<4>>
>>> <tex2html_verb_mark>1<tex2html_verb_mark>
>>> \begin<<5>>tabular<<5>><<6>>|l | <<6>>
>>> \begin<<9>>tex2html_wrap_inline<<9>>$f(x) = x^3 +  d$\end<<10>>tex2html_wrap_inline<<10>>\\     <tex2html_comment_mark>2
>>> \end<<7>>tabular<<7>>
>>> \end<<8>>document<<8>>


notice in particular:

   <tex2html_verb_mark>1<tex2html_verb_mark>

which has replaced   \verb|test|
or similar with the  {verbatim}  environment.

and   <tex2html_comment_mark>2    replacing the comment.

At a later stage of processing, the verbatim stuff
should get replaced inside  <code>...</code>  tags,
using the string stored in a file:

   .../verb_with_math_issue/TMP/verbatim

When this happens there is a message:

  *** replace markers *** 

but no further processing messages are written.


To see what is happening here for you, find the appropriate
place in the  latex2html  script, and put in more print commands,
to see what is happening in detail.

 sub replace_markers

at line  roughly  7620  and

 sub replace_sensitive_markers   at  ~7670

which calls

 sub replace_verbatim_marks    at  ~8550

and/or

 sub replace_verb_marks     at ~8590


Trace what is actually happening by putting in extra lines like

    print STDOUT $_;

at strategic places.
