Crash in mypyc with recursive tuple TypeAlias

Bug Report

Related to Issue #13795, using certain types of tuple in a recursive TypeAlias causes mypyc to crash, even though mypy reports no errors.

To Reproduce

from typing import TypeAlias

RuleItem: TypeAlias = tuple["RuleItem"] | str

def fun(value: RuleItem) -> None:
    pass

Also broken, with or without TypeAlias:

• RuleItem: TypeAlias = Union[tuple["RuleItem"], str]
• RuleItem: TypeAlias = Union[tuple["RuleItem", int], str]
• RuleItem: TypeAlias = Union[tuple["RuleItem", "RuleItem"], str]
• RuleItem: TypeAlias = Union[Tuple["RuleItem"], str]
• RuleItem: TypeAlias = Tuple["RuleItem"]

(After importing Union and Tuple from typing, of course.)

But these work:

• RuleItem: TypeAlias = Union[tuple[int], str]
• RuleItem: TypeAlias = Union[tuple["RuleItem", ...], str]
• RuleItem: TypeAlias = Union[list["RuleItem"], str]
• RuleItem: TypeAlias = Union[set["RuleItem"], str]

(That second option turns out to be what I really wanted anyway.)

Actual Behavior

The mypy command reports no errors.

Running the mypyc command on an affected file emits no output (even with a --show-traceback option) and exits with status code 245.

Running the mypyc.build.mypycify Python function on an affected file emits no output, and crashes Python with status code 139.

Your Environment

• Mypy version used: mypy 1.2.0 (compiled: yes)
• Mypy command-line flags: --strict (optional)
• Mypyc command-line flags: --show-traceback (optional)
• Mypy configuration options from mypy.ini (and other config files): None
• Python version used: 3.10.6
• OS version used: Ubuntu 22.04.1 LTS

Comienza ejecutando el ejemplo recursivo proporcionado de RuleItem con mypy y mypyc; después, inspecciona mypyc.build.mypycify y la ruta del compilador que invoca. Confirma la corrección asegurándote de que los alias afectados se compilen sin el estado 245 o 139, mientras que los alias funcionales enumerados sigan siendo válidos.
