However, in the source code, the source code runs normally, and when compiled 
and encapsulated with Cython, an exception occurs，Trigger divisible 'a = 5 // 
6'，this possibility does not exist.I checked it out :'a = 1,b = 5 / 6 + 
a'，return :'b = 0'

Closing as this is a Cython bug and not a CPython one. I also suspect this is 
triggering integer division and therefore is actually not a bug at all.
