內部編譯器錯誤和boost :: bind

Question

我正在測試具有許多函數的C ++類，這些函數基本上都具有相同的形式：

ClassUnderTest t;

DATATYPE data = { 0 };
try
{
    t.SomeFunction( &data );
}
catch( const SomeException& e )
{
    // log known error
}
catch( ... )
{
    // log unknown error
}

既然有很多，我想我應該寫一個函數來完成大部分繁重的工作：

template< typename DATA, typename TestFunction >
int DoTest( TestFunction test_fcn )
{
    DATA data = { 0 };
    try
    {
        test_fcn( &data );
    }
    catch( const SomeException& e )
    {
        // log known error
        return FAIL;
    }
    catch( ... )
    {
        // log unknown error
        return FAIL;
    }
    return TRUE;
}

ClassUnderTest t;
DoTest< DATATYPE >( boost::bind( &ClassUnderTest::SomeFunction, boost::ref( t ) ) );

但是，編譯器似乎與我不同意這是一個好主意...

我正在使用Visual Studio 2008 SP1。 如果有人指出我在做什么錯，我將不勝感激。

錯誤在您的代碼中，而不在bind 。 您傳遞的函子不包含任何參數。 代替您的電話

DoTest< DATATYPE >( boost::bind( &ClassUnderTest::SomeFunction, &t, _1) );

如果省略_1則bind將創建一個零參數函數對象，而該成員函數（期望一個數據指針）在被bind調用時將丟失一個參數。
