我正在测试我创建的 dll。它又使用其他几个 dll。当我启动测试应用程序并退出时，我的 Dll 测试程序应用程序报告内存泄漏，除了使用 LoadLibrary 加载 dll 之外没有执行任何操作。它没有显示我的 dll 源代码中的确切文件。如果我不加载 dll，就没有泄漏。它是一个 MFC dll 并具有 App 类。我从 dll 的应用程序类中删除了所有内容，因此它什么都不做，但在加载它时我仍然收到内存泄漏报告。我创建了另一组虚拟 dll 和测试应用程序，但没有报告任何泄漏，所以它与我的原始 dll 有关，也许它与其他 dll 的链接？
我尝试过使用 _crtBreakAlloc = {allocation_#}; 技术，但它也不会停止调试器。如果这种内存泄漏是真实的，我会很迷茫。我从documentation看到它可以报告误报。仅仅因为我的 dll 链接到其他一堆 dll 就可能是误报吗？我想不出其他任何东西，因为我已经注释掉了 dll 中的所有功能。
这里是内存泄漏错误

有没有其他方法可以再次检查内存泄漏不存在？我也安装了 deleaker，但它是一个有问题的程序，它保留了 pdb 文件并且没有发布它......这让我更加痛苦。
最佳答案
根据以下 MSKB 文章，这可能是预期的:
Memory leaks are reported when you use multiple MFC DLLs
从链接页面引用:
These memory leaks are reported when multiple versions of the MFC DLL are loaded in the same process. Since MFC extension (AFXDLL) DLLs require the exact same MFC DLL as the call application, this problem can only occur when using MFC regular (USRDLL) DLLs or ActiveX Controls (OCX) that use the shared version of MFC.
The most common case is mixing ANSI (MFC4xd.DLL) and UNICODE (MFC4xxUd.DLL) versions of MFC in the same process. This can also occur when mixing MFC42d.DLL and MFC40d.DLL.
就解决“问题”而言:
These memory leak notifications are false, and can be ignored. Since neither copy of MFC knows about the other ones, it's not easy to stop these false leaks from being reported.
关于c++ - 这可能是误报的内存泄漏报告吗？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23619031/
作为我的Rails应用程序的一部分，我编写了一个小导入程序，它从我们的LDAP系统中吸取数据并将其塞入一个用户表中。不幸的是，与LDAP相关的代码在遍历我们的32K用户时泄漏了大量内存，我一直无法弄清楚如何解决这个问题。这个问题似乎在某种程度上与LDAP库有关，因为当我删除对LDAP内容的调用时，内存使用情况会很好地稳定下来。此外，不断增加的对象是Net::BER::BerIdentifiedString和Net::BER::BerIdentifiedArray，它们都是LDAP库的一部分。当我运行导入时，内存使用量最终达到超过1GB的峰值。如果问题存在，我需要找到一些方法来更正我的代
我试图获取一个长度在1到10之间的字符串，并输出将字符串分解为大小为1、2或3的连续子字符串的所有可能方式。例如:输入:123456将整数分割成单个字符，然后继续查找组合。该代码将返回以下所有数组。[1,2,3,4,5,6][12,3,4,5,6][1,23,4,5,6][1,2,34,5,6][1,2,3,45,6][1,2,3,4,56][12,34,5,6][12,3,45,6][12,3,4,56][1,23,45,6][1,2,34,56][1,23,4,56][12,34,56][123,4,5,6][1,234,5,6][1,2,345,6][1,2,3,456][123
我的瘦服务器配置了nginx，我的ROR应用程序正在它们上运行。在我发布代码更新时运行thinrestart会给我的应用程序带来一些停机时间。我试图弄清楚如何优雅地重启正在运行的Thin实例，但找不到好的解决方案。有没有人能做到这一点？ 最佳答案 #Restartjustthethinserverdescribedbythatconfigsudothin-C/etc/thin/mysite.ymlrestartNginx将继续运行并代理请求。如果您将Nginx设置为使用多个上游服务器，例如server{listen80;server
ruby如何管理内存。例如:如果我们在执行过程中采用C程序，则以下是内存模型。类似于这个ruby如何处理内存。C:__________________|||stack|||------------------||||------------------|||||Heap|||||__________________|||data|__________________|text|__________________Ruby:? 最佳答案 Ruby中没有“内存”这样的东西。Class#allocate分配一个对象并返回该对象。这就是程序
导读语言模型给我们的生产生活带来了极大便利，但同时不少人也利用他们从事作弊工作。如何规避这些难辨真伪的文字所产生的负面影响也成为一大难题。在3月9日智源Live第33期活动「DetectGPT：判断文本是否为机器生成的工具」中，主讲人Eric为我们讲解了DetectGPT工作背后的思路——一种基于概率曲率检测的用于检测模型生成文本的工具，它可以帮助我们更好地分辨文章的来源和可信度，对保护信息真实、防止欺诈等方面具有重要意义。本次报告主要围绕其功能，实现和效果等展开。（文末点击“阅读原文”，查看活动回放。）Ericmitchell斯坦福大学计算机系四年级博士生，由ChelseaFinn和Chri
如何将send与+=一起使用？a=20;a.send"+=",10undefinedmethod`+='for20:Fixnuma=20;a+=10=>30 最佳答案 恐怕你不能。+=不是方法，而是语法糖。参见http://www.ruby-doc.org/docs/ProgrammingRuby/html/tut_expressions.html它说Incommonwithmanyotherlanguages,Rubyhasasyntacticshortcut:a=a+2maybewrittenasa+=2.你能做的最好的事情是:
我对如何计算通过{%assignvar=0%}赋值的变量加一完全感到困惑。这应该是最简单的任务。到目前为止，这是我尝试过的:{%assignamount=0%}{%forvariantinproduct.variants%}{%assignamount=amount+1%}{%endfor%}Amount:{{amount}}结果总是0。也许我忽略了一些明显的东西。也许有更好的方法。我想要存档的只是获取运行的迭代次数。 最佳答案 因为{{incrementamount}}将输出您的变量值并且不会影响{%assign%}定义的变量，我
你好，我无法成功如何在散列中删除key后释放内存。当我从哈希中删除键时，内存不会释放，也不会在手动调用GC.start后释放。当从Hash中删除键并且这些对象在某处泄漏时，这是预期的行为还是GC不释放内存？如何在Ruby中删除Hash中的键并在内存中取消分配它？例子:irb(main):001:0>`ps-orss=-p#{Process.pid}`.to_i=>4748irb(main):002:0>a={}=>{}irb(main):003:0>1000000.times{|i|a[i]="test#{i}"}=>1000000irb(main):004:0>`ps-orss=-p
我有一个数组数组，想将元素附加到子数组。+=做我想做的，但我想了解为什么push不做。我期望的行为(并与+=一起工作):b=Array.new(3,[])b[0]+=["apple"]b[1]+=["orange"]b[2]+=["frog"]b=>[["苹果"],["橙子"],["Frog"]]通过推送，我将推送的元素附加到每个子数组(为什么？):a=Array.new(3,[])a[0].push("apple")a[1].push("orange")a[2].push("frog")a=>[[“苹果”、“橙子”、“Frog”]、[“苹果”、“橙子”、“Frog”]、[“苹果”、“
这会导致Ruby出现内存问题吗？我知道如果大小超过10KB，Open-URI会写入TempFile。但是HTTParty会在写入TempFile之前尝试将整个PDF保存到内存吗？src=Tempfile.new("file.pdf")src.binmodesrc.writeHTTParty.get("large_file.pdf").parsed_response 最佳答案 您可以使用Net::HTTP。参见thedocumentation(特别是标题为“流媒体响应机构”的部分)。这是文档中的示例:uri=URI('http://e
