Question

我有一些ActionScript3代码，由于某种原因，只有在编译为“Release”模式时才会在堆栈溢出时崩溃。它崩溃的方法不会调用任何其他函数，因此不会以任何方式递归。奇怪的是，当在“调试”模式下编译时，它可以完美地工作。如果我在编译器选项中启用“详细堆栈跟踪”，则“释放”模式也会开始工作。这个诡计是什么？当Flash编译器尝试优化太多时，是否存在错误？

编辑：

这是堆栈跟踪：

以下是该报告中引用的一些代码：

public function selectAll(Oi:int):void
{
    var pObjectInfo:CObjInfo = OiList[Oi];
    pObjectInfo.oilNumOfSelected = pObjectInfo.oilNObjects;
    pObjectInfo.oilListSelected = pObjectInfo.oilObject;
    pObjectInfo.oilEventCount = eventProgram.rh2EventCount;

    var i:int = pObjectInfo.oilObject;
    while(i >= 0)
    {
        var pObject:CObject = ObjectList[i];
        pObject.hoNextSelected = pObject.hoNumNext;
        i = pObject.hoNumNext;
    }
}

public function filterNonQualifierObjects(rdPtr:Object, Oi:int, negate:Boolean, filter:Function):Boolean
{
    var pObjectInfo:CObjInfo = OiList[Oi];
    var hasSelected:Boolean;
    if (pObjectInfo.oilEventCount != eventProgram.rh2EventCount){
        selectAll(Oi);  //The SOL is invalid, must reset.
    }

    //If SOL is empty
    if(pObjectInfo.oilNumOfSelected <= 0){
        return false;
    }

    var firstSelected:int = -1;
    var count:int = 0;
    var current:int = pObjectInfo.oilListSelected;
    var previous:CObject = null;

    while(current >= 0)
    {
        var pObject:CObject = ObjectList[current];
        var filterResult:Boolean = filter(rdPtr, pObject);
        var useObject:Boolean = Boolean(int(filterResult) ^ int(negate));
        hasSelected = Boolean(int(hasSelected) | int(useObject));

        if(useObject)
        {
            if(firstSelected == -1){
                firstSelected = current;
            }

            if(previous != null){
                previous.hoNextSelected = current;
            }

            previous = pObject;
            count++;
        }
        current = pObject.hoNextSelected;
    }
    if(previous != null){
        previous.hoNextSelected = -1;
    }

    pObjectInfo.oilListSelected = firstSelected;
    pObjectInfo.oilNumOfSelected = count;

    return hasSelected;
}

Answer 1

您是否在代码中的任何位置使用跟踪？跟踪功能有两个可能的问题。首先，跟踪会在运行时延迟并影响异步进程。第二，可能在跟踪函数中调用了一些方法。此方法可以更改变量的值。

因此，您可能会删除一些跟踪并检查代码是否会在发布模式下崩溃。

您的问题可能是由此错误引起的：http://bugs.adobe.com/jira/browse/ASC-2993
