On SUN Warning: A non-POD object of type ... passed as a variable argument to function "testing::internal::IsNullLiteralHelper(...)".

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compiler the program below by "CC runner.cpp gtest-all.cc"

#include "gtest/gtest.h"
#include <string>

TEST(String, POD) {
  std::string a("x"), b("y");
  EXPECT_EQ(a, b);
}

int main(int argc, char* argv[]) {
  testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}

What is the expected output? What do you see instead?

It should not print out any compilation warnings. But it prints:

runner.cpp:
"runner.cpp", line 7: Warning: A non-POD object of type "std::string " 
passed as a variable argument to function 
"testing::internal::IsNullLiteralHelper(...)".
1 Warning(s) detected.
