Redirect system2 stdout to a file on windows

According to the manual, the stdout argument of the system2 function can redirect output to a file. This seems to work on unix, however I can't get it to work on windows. The toy example below, no out.txt or err.txt files are created. I tried sending it to an existing file, or expand the full file path, but with no success:

setwd(tempdir())
system2("whoami", stdout="out.txt", stderr="err.txt")
file.exists("out.txt")

Am I doing something wrong or is this a limitation in system2 ?

I'm quite convinced now this is a bug in RGui.exe in windows. I filed a bug report here: https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=15393
