Issue 1782: Test case where pypy is more than 4x slower than CPython
https://bitbucket.org/pypy/pypy/issue/1782/test-case-where-pypy-is-more-than-4x
Armin Rigo:
Simplified test case: this runs in 1.1 seconds on CPython, 5.8 seconds on "PyPy
--jit off", and seems never to finish on PyPy (out of ram after 2 minutes):
def g(n):
if n > 0:
for x in g(n-1):
yield x
for x in g(n-1):
yield x
else:
yield 0
list(g(20))
