什么会导致这样的 'doubled' 堆栈？

Question

一位用户报告了使用我们的 SDK 构建的 ODBC 驱动程序崩溃，并提供了两个核心转储。我将在下面提供堆栈跟踪：

第一次崩溃：

他们将驱动程序与 SAS 一起使用，并且在两个堆栈跟踪中，它看起来像是要调用 ICU（我们自己构建它并添加 'sb' 前缀），但它却以某种方式（通过这 4 帧垃圾[我假设调试器没有正确展开堆栈？？？]）回调到 SAS？

我认为堆栈只是损坏了或什么的，但在第一个中，崩溃是由当前未使用给定语句的断言引起的（断言永远不会失败），但是，查看调试器，传递给 odbc32.dll!SQLPrepareCover() 'below' 的句柄与传递给 odbc32.dll!FreeStmt() 'above' 的句柄相同，因此断言会失败，因为我们能够再次锁定我们的互斥量（它们是递归的）并重新进入它不应该出现的地方。

除了 SAS 使用光纤或其他某种绿色线程外，我想不出任何会导致这种情况的原因？还是信号处理程序？（但我认为 windows 的工作方式不同，我认为它会出现在堆栈上）。 ICU 的某些函数指针 table 是否被损坏以某种方式指向 SAS？ ICU & SAS 应该对彼此一无所知。

Answer 1

忘了这个问题。

问题最终是由 sas 安装的 seh 处理程序引起的，它被触发是因为 sas 启用了浮点异常，然后调用了驱动程序。 ICU没想到会启用fp异常，触发了一个，然后sas cleanup crash了进程

什么会导致这样的 'doubled' 堆栈？

What can could cause a 'doubled' stack like this?

c++

crash

odbc
