The linearize command is broken, fails with Prelude.(!!): index too large.

[GoogleCodeExporter]

The linearize command is broken in both the GF shell and the PGF web service. 
Instead of producing the expected linearizations, it fails with Prelude.(!!): 
index too large.

What steps will reproduce the problem?
---------------------------------------------------------------------
cd examples/foods
make
gf Foods.pgf
Foods> l -treebank Fish
Foods: Fish
FoodsAfr: daardie vis
FoodsAmh: ያ ዓሳ
Prelude.(!!): index too large
--------------------------------------------------------------------
cd examples/phrasebook
make
gf Phrasebook.pgf
Phrasebook> gr | l -treebank
Phrasebook: PGreetingMale GGoodLuck
Prelude.(!!): index too large

Here is a stack trace from a simple translation program using the Phrasebook.

More details on how to trigger this problem with the Foods grammar:

$ gf -make -src -optimize-pgf FoodsBul.pgf
$ gf Foods.pgf
> l Fish
Prelude.(!!): index too large

--------------------------------------
Buf if you omit -optimize-pgf it doesn't happen

$ gf -make -src FoodsBul.pgf
$ gf Foods.pgf
> l Fish

the pgf optimization was ignoring the linref definitions
