Can you point me to where the actual fix is? All I see in the diff are test changes.

Ah yeah, it was just this line: https://github.com/jneen/parsimmon/pull/283/files#diff-d6843052e5b691e32d17eb1fb2508987L216

 function parseBufferFor(other, length) {
-  ensureBuffer();
   return new Parsimmon(function(input, i) {
+    ensureBuffer();
     if (i + length > input.length) {
       return makeFailure(i, length + " bytes for " + other);
     }

I'm waiting until the parse actually happens to report the error. This is needed because this was getting called by the setup of the int8LE and whatnot.

And yeah when I ws getting Karma working Mocha started getting mad that the tests were using mixed TDD/BDD syntax
