What steps will reproduce the problem?
1. For extra info, something like,

diff --git a/base/files/scoped_temp_dir.cc b/base/files/scoped_temp_dir.cc
index a04e825156b6..e62f5527ac2e 100644
--- a/base/files/scoped_temp_dir.cc
+++ b/base/files/scoped_temp_dir.cc
@@ -21,7 +21,7 @@ ScopedTempDir::ScopedTempDir() {

 ScopedTempDir::~ScopedTempDir() {
   if (!path_.empty() && !Delete())
-    DLOG(WARNING) << "Could not delete temp dir in dtor.";
+    PLOG(WARNING) << "Could not delete temp dir in dtor." << path_.value();
 }

 bool ScopedTempDir::CreateUniqueTempDir() {


2. run $ content_unittests --gtest_filter=MacSandboxTest.*

What is the expected result?

No warnings about leaked folders


What happens instead of that?

17 leaked tempdirs: `ls -d ${TMPDIR}/.org.chromium.Chromium*`

Output like
