Memory leaks 如何破译可视泄漏检测器报告的内存泄漏

有人能帮助破译可视泄漏检测器报告的内存泄漏吗

它在openssl中的某个地方吗

还有，当没有这样的驱动器映射时，为什么它引用驱动器

f:

上的文件

类似的研究表明，这可能与为初始化分配一次的内存有关

它指向f:因为这些路径保存在调试信息中。构建CRT时，源被放置在驱动器f:

我认为这是一个不应该（也不能）修复的漏洞，它看起来像是一次初始化

无论如何，我也建议尝试其他第三方工具，发现内存泄漏，也许你会得到更多的信息

它在openssl中的某个地方吗

是的，OpenSSL已知内存泄漏。例如，请参见OpenSSL和

这可能会（也可能不会）导致您的问题

可能还有其他人

有人能帮助破译可视泄漏检测器报告的内存泄漏吗

对不起，我帮不了你

还有，当没有这样的驱动器映射时，为什么它引用驱动器f:上的文件

Microsoft的调试记录包括路径。例如，请参见

但它对您没有帮助，因为您没有Microsoft的构建环境。这是可以忽略的
