New issue 3115: pyp2.7-v7.2.0 json loads error https://bitbucket.org/pypy/pypy/issues/3115/pyp27-v720-json-loads-error
zhaoqinghui: I build pypy2.7-v7.2.0 from source under docker centos7 When I used it to read a simple JSON file, an error occurred, if I use python or pypy2.7-v6.0.0 there is no problem. I made a simple test case to reproduce this error this is the output: ``` [root@14208e811d5c ~]# pypy a.py <type 'dict'> 2 payment Traceback (most recent call last): File "a.py", line 23, in <module> pp(d) File "a.py", line 16, in pp print v TypeError: 'NoneType' object is not iterable ``` this is my test a.py file: ```python # -*- coding=utf-8 -*- import inspect, json f = open('./a.json') l = f.read() f.close() d = json.loads(l) print type(d), len(d) def pp(o): if isinstance(o, dict): for k, v in o.items(): print k print v pp(v) if isinstance(o, list): for x in xrange(len(o)): print o[x] pp(d) ``` The a.json used in the test is a little large, so I put it in the attachment this is my os info in docker : ``` [root@14208e811d5c ~]# pypy --version Python 2.7.13 (4a68d8d3d2fc1faec2e83bcb4d28559099092574, Nov 13 2019, 06:25:39) [PyPy 7.2.0 with GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] [root@14208e811d5c ~]# cat /etc/redhat-release CentOS Linux release 7.7.1908 (Core) [root@14208e811d5c ~]# uname -a Linux 14208e811d5c 4.9.184-linuxkit #1 SMP Tue Jul 2 22:58:16 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux [root@14208e811d5c ~]# c++ -v Using built-in specs.
