The error in mpxerr.log is:

The problem is that the \zerocount that is used in buildrel: \def\buildrel#1\over#2% {\mathrel{\mathop{\kern\zerocount#2}\limits^{#1}}} somehow ends up being a \chardef. A shorter test file is: \starttext $\buildrel a \over b $ \stoptext the weird thing is that I can't figure out where that definition takes place ?? (well, there is one in syst-ini, but that should have been overwritten by the one in syst-gen, afaik). Best wishes, Taco
