*RemoveFileOnSignal=*/false
Traced back to ad7aaa475e5e632242b07380ec47d2f35d077209
A simplified command line is as follows:
clang-cl -fno-temp-file /Yc /Fpstdafx.pch /Fostdafx.obj stdafx.h
Observer in your favorite system monitor (such as procmon) that a temp file is
created.
Without hacking up our internal fork of clang this completely blocks adoption
