New issue 2229: Encountered RPython error

Chuancong Gao:

I keep encounter this error in latest version of PyPy. However, the code works fine in latest version of CPython. When I change the number of lines read and the number of iterations, the problem is solved. 

Sorry I cannot share the private code. I will see if I can minimize the code to make it public.
