Crash report

In a--with-pydebug build, run the following code:

$ cat ~/tmp/t.pyimport astast.parse("""func(    a=["unclosed], # Need a quote in this comment: "    b=2,)""")$ ./python ~/tmp/t.py

Error messages

python: Objects/call.c:324: _PyObject_Call: Assertion `!_PyErr_Occurred(tstate)' failed.fish: Job 1, './python ~/tmp/t.py' terminated by signal SIGABRT (Abort)

(How do I obtain a core dump?)

I think the error happens inside this call:

What happened is that the_PyTokenizer_Get(p->tok, &new_token) call earlier also sets an errorhere.

Your environment
