compilation - Python: getting segmentation fault when using compile/eval -

code:

import ast  globalsdict = {}  fast = ast.functiondef(     name="foo",     args=ast.arguments(args=[], vararg=none, kwarg=none, defaults=[]),     body=[], decorator_list=[])  exprast = ast.interactive(body=[fast]) ast.fix_missing_locations(exprast) compiled = compile(exprast, "<foo>", "single") eval(compiled, globalsdict, globalsdict)  print globalsdict["foo"] 

with both cpython , pypy, getting segmentation fault. why?

---

• cpython bug report
• pypy bug report
• abstract syntax trees documentation

i guess function definition must not have empty body. tested code adding no-op statement function body:

fast = ast.functiondef(     # ...     body=[ast.pass()],     # ... 

and segmentation fault gone; output is:

<function foo @ 0x022db3f0>

if correct, bug in ast module, since should check empty body.
