--- Comment #1 from Iain Buclaw <ibuclaw at gdcproject.org> ---
What happens is that in dmd.typesem, it sees the identifier __builtin_va_list,
and blindly sets the type to `void*`, rather than using the already defined
alias that resolves to the correct type.

PR that introduced this behaviour: https://github.com/dlang/dmd/pull/13107
