Conflict between stackengine and babel with spanish option

Question

When pdfLaTeXing the MWE below I get a Missing \endcsname inserted error message. The compilation proceeds with no errors as soon as the babel package is not loaded with the spanish option (well, to be true, I've only tried with the english option, and it works alright). Any hints on how to solve this issue, or on a possible workaround, would be welcome.

Follows the MWE:

\documentclass{memoir}

\usepackage{stackengine}
\usepackage[spanish]{babel}

\begin{document}
\Shortstack[c]{A N E}
\end{document} 

EDIT: I've just tried with the es-noquoting option and with the coupled commands \deactivatequoting-\activatequoting, as suggested in some posts about issues related to spanish babel, but to no avail. The problem remains the same.

Answer 1

stackengine uses the command \roman in a csname (which is simply not a good idea: \roman is for printing and not for the generation of command names) and this breaks as spanish redefines \@roman. As a workaround you can disable the redefinition but imho stackengine should be corrected.

\documentclass{memoir}
\usepackage{stackengine}
\makeatletter
\let\ori@roman\@roman
\usepackage[spanish,]{babel}
\let\@roman\ori@roman


\begin{document}
\Shortstack[c]{A N E}
\end{document}
