调试使用Python 3.6编译的_unicode错误——带有pydebug

Question

我已经编译了python3.6，但是出现了一些错误，导致下面的代码失败

Python 3.6.0+ (default, Feb 25 2017, 12:10:05)
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.42.1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import _crypt
>>> _crypt.crypt('', '')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfb in position 1: invalid start byte

我应该在哪里调试它？你知道吗

_crypt扩展看起来没有问题。。。你知道吗
