Transforming a long list cause IronPython crashes #1260

Open xiaxinmeng opened 3 years ago

xiaxinmeng commented 3 years ago

See the following example, we transform the map l into list, and then IronPython crashes.

test.py

import operator

N = 500000
l = [0]

for i in range(N):
    l = map(operator.add, l, [1])

print(list(l))
