To repro run the following commands against an empty db.

> db.tri.ensureIndex(

{ c: '2d', t: 1 }

,

{ min: 0, max: Math.pow(2, 40) }

)
> db.tri.insert(

{ c : [1,1], t : 1}

)
point not in range
> db.system.indexes.find()
{ "name" : "id", "ns" : "localhost.tri", "key" :

{ "_id" : 1 }

, "v" : 0 }
{ "_id" : ObjectId("4d796ffa3996d83589c67397"), "ns" : "localhost.tri", "key" :

{ "c" : "2d", "t" : 1 }

, "name" : "c__t_1", "min" : 0, "max" : 1099511627776 }

So we're creating a Geo index with a very large max. It's obviously not too large as the index correctly saves / displays the number. However, when we insert data, that index throws the "point not in range" error.

Math.pow(2,30) => works correctly
Math.pow(2,31) => breaks

(integer vs numberlong issue?)
