Description

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

Research direction

Reproduce the failures from the listed PCBuild commands using the MSVC ASAN configuration, starting with test_call and test_functools. Inspect test/test_functools.py around line 2088 and the failing test output to determine the scope of the stack-overflow behavior. Done means the affected tests pass reliably under this configuration without the reported ASAN failures.
