In your PR, the "Checks" tab shows that this breaks the build for all
non-32-bit Linux builds and for Windows. Here is an excerpt of the failed
`linux-clang` build:

Could you fix those compile errors, please?

While at it, please also fix your author email: it should match your
_real_ email address, i.e. "liamhuang0205@gmail.com", not
"Liam0205@users.noreply.github.com".

Thank you,
