This throws errors. Any idea why?

$\xrightoverleftarrow{}{33=C2=B0C}$

This does work. Sadly it is not = the arrow I want to have.

MWE:

\starttext
$A = \xrightarrow{}{} B$
\stoptext

No problem here.

It = seems to be a problem with the font I use.  Hans, do you have any = idea why that does not work if I am using Minion Math? I am getting the = following error:
