描述
The Lib/test/crashers directory contains some Python files that are known to crash the interpreters. I thought it'd be useful to check in on whether they are still crashing the interpreter.
Here's what I get on a current-ish 3.14 build:
bogus_code_obj.py: TypeError because we're missing some arguments to the CodeType constructor. I assume this would still crash if you pass the missing args though.gc_inspection.py: segfaultinfinite_loop_re.py: takes a long time (this is not exactly a crasher, just a ReDoS)mutation_inside_cyclegc.py: no errorrecursive_call.py: hangs for a long time (this sets the recursion limit to a huge value and then does runaway recursion). I believe Mark Shannon's recent interpreter changes make it so this doesn't segfault. Interestingly, I can't kill the process with Ctrl-C, maybe a bug?trace_at_recursion_limit.py: RecursionError (which is not a crash)underlying_dict.py: segfault
I'll send a PR to make bogus_code_obj.py properly segfault again. Some of the other ones should perhaps be removed.

调研方向
检查 Lib/test/crashers 中列出的文件,从 bogus_code_obj.py、gc_inspection.py、mutation_inside_cyclegc.py、recursive_call.py、trace_at_recursion_limit.py 和 underlying_dict.py 开始。在当前的 CPython 构建上运行它们,并将其行为与 issue 报告进行比较,同时检查关联的 PR gh-121922 和 gh-126360。根据 crashers 当前的行为对其进行更新或删除,即表示完成。
