描述

Hi,

Cpython failed to run test_call test_functools tests with ASAN using MSVC on windows, it can be reproduced on 151d1bf commit on main branch. Could you please help look at this issue? Thanks in advance.

Steps to reproduce the behavior:

  1. git clone https://github.com/python/cpython
  2. Open VS2022 x64 CMD & set CL= /fsanitize=address /GS- /wd5072 & set LINK= /InferASanLibs /incremental:no /debug
  3. cd /d C:\gitP\python\cpython\PCBuild
  4. get_externals.bat --clean-only
  5. build -e -p x64 -r --no-tkinter -v "/p:PlatformToolset=v143" "/p:WindowsTargetPlatformVersion=10.0.26100.0"
  6. rt -p x64 -q -x test_asyncio test_distutils test_importlib test_peg_generator test_tools test_socket test_compileall test_int test_sys test_venv test_embed test_urllib2net test_capi test_userdict

研究方向

使用 MSVC ASAN 設定重現所列 PCBuild 指令的失敗,先從 test_call 和 test_functools 開始。檢查 test/test_functools.py 第 2088 行附近的內容以及失敗測試的輸出,以判定堆疊溢位行為的範圍。在此設定下,受影響的測試能夠穩定通過且不再出現回報的 ASAN 失敗,即視為完成。
