[ZODB-Dev] Problem Storing Infinity

[Chris S]

I'm having a problem storing infinity. The following code reproduces
the problem on w2k:

from ZODB import FileStorage, DB
from persistent import Persistent
from persistent.mapping import PersistentMapping as dict
import transaction

storage = FileStorage.FileStorage('zodb.db')
db = DB(storage)
conn = db.open()
root = conn.root()
try:
    root['data'] = 1e99999999
finally:
    transaction.commit()
    conn.close()
    db.close()
    storage.close()

Traceback (most recent call last):
