Compiler RecursionError more likely to occur in 3.13

Bug report

Bug description:

Reference: https://github.com/sympy/sympy/issues/26692

There's a long expression in sympy that's causing a RecursionError in ast.c. The source of the RecursionError is https://github.com/python/cpython/blob/ffc8e21c80627c46be7a7467ee5427924fdeb885/Python/ast.c#L217.

This seems to happen with a 3.13 debug build due to a lower recursion limit. The error doesn't happen in 3.13 release.

Interestingly, the error doesn't happen in the 3.12 debug build, even though the recursion limit appears to be the same. This leads me to believe that 3.13 is causing more recursive calls than expected. I think we should investigate why 3.13 is making additional calls and/or raise the recursion limit.

Simple repro:

import ast
contents = "x = " + " * ".join(["1"] * 2000)
result = ast.parse(contents)

On 3.12 debug, this code runs fine. On 3.13 debug, this code causes a RecursionError even when we change 2000 to 500 (leading me to believe that it is not the case that 3.13 is just adding a constant number of additional calls).

CPython versions tested on:

3.12, 3.13

Operating systems tested on:

Linux

首先在 3.12 和 3.13 的 debug 构建中使用 ast.parse 重现该表达式，然后检查 Python/ast.c 中报告的第 217 行附近的递归检查。确定 3.13 为什么会进行额外的递归调用，或者递归限制是否不恰当；完成的标准是解决该回归问题，并验证所提供的重现不再失败。
