problem with extract method from gtest test case

I'm working on the GildedRose refactoring kata (https://github.com/emilybache/GildedRose-Refactoring-Kata) and I've so far got this test code:

TEST(GildedRoseTest, Foo) {
    auto *name = "Foo";
    int sellIn = 0;
    int quality = 0;

    vector<Item> items;
    items.push_back(Item(name, sellIn, quality));
    GildedRose app(items);
    app.updateQuality();
    auto &result = app.items[0];

    EXPECT_EQ("Foo", result.name);
}

I would like to perform an'extract method' refactoring on the middle block of code here, which should create a function
that I can reuse in several test cases. When I select "extract method" from the refactoring menu it works out
the signature of the new function should be this:

Item GildedRoseTest_Foo_Test::getItem(const char *name,
                                      int sellIn,
                                      int quality) const

When I push the "extract" button to ask it to do the refactoring, it completely mangles the code and nothing compiles 
any more:

TEST(GildedRoseTest, Foo)

    Item getItem(const char *name, int sellIn, int quality) const
    {
        return Item(__1::basic_string(), 0, 0);
    }

{
    auto *name = "Foo";
    int sellIn = 0;
    int quality = 0;

    vector<Item> items;
    items.push_back(Item(name, sellIn, quality));
    GildedRose app(items);
    app.updateQuality();
    auto &result = app.items[0];

    EXPECT_EQ("Foo", result.name);
}

Item GildedRoseTest_Foo_Test::getItem(const char *name, int sellIn, int quality) const
{
    vector<Item> items;
    items.push_back(Item(name, sellIn, quality));
    GildedRose app(items);
    app.updateQuality();
    auto &result = app.items[0];
    return result;
}

I can of course fix this up with a little work, but I might have well have not used the automated refactoring tool in
the first place.

Am I doing something wrong or how should I get extract method to work?
