+// This is a regression test for handling of stat caches within the tooling
+// infrastructure. This test reproduces the problem under valgrind:
+
+// First, create a pch that we can later load. Loading the pch will insert
+// a stat cache into the FileManager:
+// RUN: %clang -x c++-header %S/Inputs/pch.h -o %t1
+
+// Use the generated pch and enforce a subsequent stat miss by by using
+// the test file with an unrelated include as second translation unit:
+// Do not directly pipe into FileCheck, as that would hide errors from
+// valgrind due to pipefail not being set in lit.
+// RUN: clang-check "%S/Inputs/pch.cpp" "%s" -- -include-pch %t1 -I "%S" -c >%t2 2>&1
+// RUN: FileCheck %s < %t2
+
+#include "Inputs/pch-fail.h"
+
+// CHECK: Processing
+
+// FIXME: This is incompatible to -fms-compatibility.
+// XFAIL: win32
