Go to asciimath.org. Type "vec()". You will get a Math Processing Error.
This message will persist even when you replace "vec()" with something valid.
When I try to replace "vec()" by something, I get errors in the console (Chrome).
This issue seems to be exclusive to the "vec" operation. Typing "hat()" will not cause any issue, and neither will "tilde()" or "bar()" or "dot()" etc.
I see the likely cause in ASCIIMathML.js. I can fix it here, but it will take a while (often months) for changes here to make their way upstream to MathJax.
