New submission from Yuv Gre <[email protected]>:
I'm using Python 3.1.2 (r312:79149, Mar 21 2010, 00:41:52) [MSC v.1500 32 bit
(Intel)] on win32. Running the following code:
import profile
import math
import decimal
def show_bug():
x = decimal.Decimal.from_float(math.e)**(-2**31)
profile.run('show_bug()')
And I get this stack trace:
Traceback (most recent call last):
