astyle_1.15.3的源码有BUG吗？_astyle bug-优快云博客

本文介绍了一个基于对话框的VC程序在使用astyle时出现的内存泄露问题。问题出现在ASBeautifier类的析构函数中，部分动态分配的内存未被正确释放。通过增加DestroyAllVector函数并调整析构函数逻辑，成功解决了内存泄露问题。

VC中基于对话框的程序使用astyle，运行后居然报内存泄露：
Detected memory leaks!
Dumping objects ->
{44} normal block at 0x00450030, 33 bytes long.

…………………………
Object dump complete.

原因是 ASBeautifier::init() 初始化了13个指针，ASBeautifier::~ASBeautifier() 只释放了9个
原代码：
ASBeautifier::~ASBeautifier()
{
    DELETE_CONTAINER( headerStack );
    DELETE_CONTAINER( tempStacks );
    DELETE_CONTAINER( blockParenDepthStack );
    DELETE_CONTAINER( blockStatementStack );
    DELETE_CONTAINER( parenStatementStack );
    DELETE_CONTAINER( bracketBlockStateStack );
    DELETE_CONTAINER( inStatementIndentStack );
    DELETE_CONTAINER( inStatementIndentStackSizeStack );
    DELETE_CONTAINER( parenIndentStack );

    //DELETE_CONTAINER( sourceIterator );
}

修改后代码：
ASBeautifier::~ASBeautifier()
{
    DestroyAllVector(tempStacks);

    DELETE_CONTAINER( waitingBeautifierStack );
    DELETE_CONTAINER( activeBeautifierStack );
    DELETE_CONTAINER( waitingBeautifierStackLengthStack );
    DELETE_CONTAINER( activeBeautifierStackLengthStack );

    DELETE_CONTAINER( headerStack );
    DELETE_CONTAINER( blockParenDepthStack );
    DELETE_CONTAINER( blockStatementStack );
    DELETE_CONTAINER( parenStatementStack );
    DELETE_CONTAINER( bracketBlockStateStack );
    DELETE_CONTAINER( inStatementIndentStack );
    DELETE_CONTAINER( inStatementIndentStackSizeStack );
    DELETE_CONTAINER( parenIndentStack );
}

// Added by truezq
void DestroyAllVector(vector< vector<const string*>* > *pAllVector)
{
    if (pAllVector == NULL) return;
    int i;
    for (i = 0; i < pAllVector->size(); ++i)
    {
        //vector<const string*>* pVec = ;
        delete (*pAllVector)[i];
    }

    DELETE_CONTAINER( pAllVector );
}

---------------
最后还发现报memory leaks
原因是VC自带的STL有问题，误报，使用STLPORT后没有此现象。
