New submission from Yuan Chao Chou:
When Parser/asdl_c.py is composing the content of Python/Python-ast.c, it uses
"value" to name the variables in inner blocks, which can shadow the variables
named the same in outer blocks. It would be a good practice to avoid the
shadowing naming

Yuan Chao Chou added the comment:
This can be repro by setting -Wshadow-compatible-local when using gcc to
compile Python-ast.c.
An example on my machine:
➜ cpython git:(69c0db5050) ✗ gcc-7 -Wshadow-compatible-local
-Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -g -fwrapv -O3
