I can see that this issue, as well as the other one you mentioned, comes up with `printf.exe` supplied by GnuWin32. However, GnuWin32 has a big red warning on top of its webpage that "As of January 2024 this project is no longer functional. Please see the README for more information." Previously, up to LLVM 13, LLVM documented that GnuWin32 should be used (https://releases.llvm.org/13.0.0/docs/GettingStartedVS.html). This was changed in 2021, for LLVM 14, to say "You will need Git for Windows with bash tools, too." (https://releases.llvm.org/14.0.0/docs/GettingStartedVS.html) Can you please check that you're not still using the GnuWin32 tools?
