[pypy-dev] Differences between pypy2 and 3 and cffi

Hi,
I have an embedded function:
@ffi.def_extern()
def toint(input,insize,result):
for i in range(insize):
x = ffi.string(input[i])
result[i] = float(x) if x else 0
return 1
It seems that this runs around 30-40% percent slower in PyPy3 than in 2.
Input is a char** c array and result is a float c array. The difference is not in ffi.string
If having `result[i] = 1 if x else 0` it runs same in both versions. Any ideas?
