conflict between microtype and asme2e.cls

Question

The microtype package seems to glitch with the asme2e.cls class file. The MWE is as follows:

\documentclass[twocolumn,10pt]{asme2e}
\usepackage{microtype} % comment/uncomment
\title{Title}
\begin{document}
\maketitle
\end{document}

with:

The beginning of the error message is as follows:

\MT@prot@iffirstcmd ...\MT@prot@next \relax \@nil 
                                                  #1\expandafter \expandafte...
l.6 \maketitle

What is your experience with this (fairly recent) issue?

You've been here long enough to know to always add a minimal example others can copy and test as is (and no, I did not give negative score) — daleif

questions should not rely on the content of external links. please provide an MNWE here and the full message from the log (which should include a line number). also specify which engine you're using. — cfr

an mwe based on the versions I have in tl works for me and you don't say which version you think causes the problem. — cfr

Workaround: \documentclass[twocolumn,10pt]{asme2e} \usepackage{microtype} % comment/uncomment \title{Title} \begin{document} \microtypesetup{nopatch=item} \maketitle \microtypesetup{patch=item} \end{document} — samcarter_is_at_topanswers.xyz

I am answering to change the status of the question. A fix has been suggested by Robert in the dev branch of the microtype package.
