This may not return, since in a subroutine. We may need to return. Please double
check.

I think is rvh is FALSE, the test immediately finishes with failure. We don't
need to care about it.

(But I'll ask C++-guys to take a look at the C++ code later)

@hashimoto told me about this problem, so you may want to ask him.

[yoshiki, 2013/10/31 11:05:29]

I asked @hashimoto and we only concluded that that @satorux may have better
idea.

[hashimoto, 2013/11/01 08:15:47]

As long as RunTest() is called at the last of each test, I see no problem in
this code.
If any code follows RunTest(), it might be better to use
ASSERT_NO_FATAL_FAILURE(RunTest(...)).
Yoshiki, the problem you are mentioning here is about the name of this test,
right?

Sorry, I misunderstood. You're right.
