689963.patch

Proposed patch to resolve this. In z11_enumerate_glyph, check the requested
index
against the number of glyphs in the CMap. If the requested glyph index exceeds
the count of glyphs, return a rangecheck error.

I'm still sorting out getting my regression test working on the cluster (its
all my fault), but a local regression test shows no differences.
