I listed DLL exports in the Visual Studio Command Prompt:dumpbin /exports \vstinner\python\master\PCbuild\amd64\python38_d.dll > \vstinner\python\exports.txtTo make sure that I don't mess with commands, I started with a fresh Git checkout using:git clean -fdxPCbuild\build.bat -d -p x64 -eGood news: usingPR 12853, exports.txt is exactly the same file (I expected memory address to change, but nope, they are the same). My change doesn't introduce any new symbol. See attached exports.txt file. By the way, there is no symbol which contains "PyInit" nor "Py_pickle_init" in DLL exports.
