Summary: Import value 1e400  from pyc fails

Initial Comment:
-------------------------------------------
#file: bug.py
#sys.version_info (2, 4, 2, 'final', 0)
#Platform is Windows XP

import sys, bug
infinity = 1e400

if __name__ == "__main__":
    import bug
    print "Infinity is", bug.infinity

------------------------------------------

This code behaves correct using bug.py - when bug.pyc
is not up to date / not exists:

 Infinity is 1.#INF

and behaves wrong using bug.pyc - when bug.pyc is up to
date:

 Infinity is 1.0

This is a known bug with Python and floating point infinity
literals.

You can use:
infinity = 1e155 * 1e155

I believe this is fixed in the latest Python 2.5 SVN.
