Stijn, I'm not sure if you ever found the resolution.

You can see the loop, \makebm ends up calling itself.
Evidently \makebm cannot be used in \everymath. Even a complete re-archiTeXture will not help :).
The problem is this: When bm encounters a group such as happens in this case in the superscript, it will call \bm@mchoice defined thusly: \def\bm@mchoice#1#2#3#4#5{% \mathchoice{\hbox{#1$\displaystyle\m@th#2$}}% {\hbox{#1$\textstyle\m@th#3$}}% {\hbox{#1$\scriptstyle\m@th#4$}}% {\hbox{#1$\scriptscriptstyle\m@th#5$}}} Exiting and entering mathmode like this triggers \everymath and so our infinite recursion is started. Easiest remedy is to also tell \everymath to reset itself. \renewcommand*\descriptionlabel[1]{% \hspace\labelsep {\everymath{\everymath{}\makebm}\normalfont\bfseries #1:}% } -- Morten
