Biased suggestion: implement support for Schrödinger's Token (see the
paper in Software -- Practice & Experience 31, 8 (2001), pp. 803-814).

Unbiased suggestion: I'm not sure what flavor of the GLR algorithm
you're using, but some have (fixable) problems with some grammars.  Offhand,
I'd check infinite recursion (A -> A) and hidden left recursion.
