Cpython build failed with error LNK2001: unresolved external symbol on windows, this error looks start from commit 10f950c9bb0ff4583f361a42aaed562b330e1dba, the previous commit 9846407eaf385917d134ef5e3700c57c59f67684 built successfully.

Repro steps:

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"

Piste de recherche

Commencez dans PCBuild et sur la cible python3tdll.vcxproj, en reproduisant l’échec avec VS2022, ASan et la commande de compilation fournis. Comparez le commit 10f950c9bb0ff4583f361a42aaed562b330e1dba au commit 9846407eaf385917d134ef5e3700c57c59f67684 afin d’identifier la modification de la configuration du linker Windows ; le travail est terminé lorsque la compilation x64 avec ASan s’achève sans unresolved externals.
