In the following example, it is the ";" that leads to the error

If you suppress it, it works fine. (???)
Taco, the error also occurs with cambria. So, by your definition, it is
an engine error.
It isn't, it is caused by the lua postprocessing of math lists that
does not deal with choice nodes properly. Hans should fix the lua
code, but meanwhile I do have an 'almost' engine-level solution:
\def\mathchoice#1#2#3#4%
{\ifcase\mathstyle#1\or#1\or#2\or#2\or#3\or#3\or#4\or\#4\fi}
Best wishes,
Taco
