fstream include removed while required

Question

Originally reported on Google Code with ID 90

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

I run include-what-you-use on a large source file containing Google Test test cases.
On this particular file, there is a class extending 'testing::Test', which has protected
members of type 'ifstream'. As a result, an include is needed: '#include <fstream>'

However, IWYU suggests removing the '<fstream>' include, and I can't find out why.
I've created a smaller test case.


What version of the product are you using? On what operating system?
I'm afraid I'm using an older IWYU version (revision 352), since I had issues compiling
the newer version.
I'm running Ubuntu Linux 64-bit.

Please provide any additional information below.

Answer 1

Note: in the smaller test case, '<fstream>' is not present. It's needed for compilation,
but IWYU does not suggest to add it.

If you add '#include <fstream>', IWYU suggests to remove it.
