The problem is in the LaTeX export for wxMaxima, which is managed as a separate project from Maxima itself. I've closed this bug report and assigned it to andrejv (wxMaxima project administrator) so that it comes to his attention.
Sorry for the confusion. Maybe there is a way to reassign bugs from one project to another but I don't know what it is.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
If you could give the input that produces this output, it might help us find the problem,
Another thing: are you using the wxMaxima "copy as LaTeX" or do you
see this from a Maxima output line?
For example
(%i1) eq:y=x^2;
(%o1) y=x^2
after export as *.tex
or Ctrl+A copy as latex
we get lines
\begin{math}\displaystyle
\mathrm{\color{labelcolor}(\%o1) }\quady={x}^{2}
\end{math}
\quady - undefined latex command
Maxima 5.21.1 on windows7
