I neither can reproduce it in my Ubuntu, but analyzing the problem...
what about this?:
d = {}
for i in range(10000):
val = -19400000000 * (1/100.0)
d[val] = d.get(val, 0) + 1
or
d = {}
for i in range(10000):
val = -19400000000 * (1/100.0)
d.setdefault(val, []).append(i)
I think that is interesting to know,,,
- if in these structures the problem still happens...
- how many values go for each key, and which values.
