New submission from Batuhan Taskaya <isidenti...@gmail.com>:
import ast
t = ast.fix_missing_locations(ast.Expression(ast.Name("True", ast.Load())))
compile(t, "<t>", "eval")
compilation of this AST can crash the interpreter for 3.8+
test_constant_as_name (test.test_ast.AST_Tests) ... python:
Python/compile.c:3559: compiler_nameop: Assertion
`!_PyUnicode_EqualToASCIIString(name, "None") &&
!_PyUnicode_EqualToASCIIString(name, "True") &&
!_PyUnicode_EqualToASCIIString(name, "False")' failed.
Fatal Python error: Aborted
I've encountered this while running test suite of 'pytest' with the current
master, so I guess there are some usages related this out there. IMHO we should
validate this on the PyAST_Validate step to prevent this kind of crashes.
