无效异常展开导致崩溃
Crash caused by invalid exception unwinding?
我正在调试一个在我们的一个测试中发生的崩溃。我们有一个用C++编写的ODBC驱动程序，它正在通过iODBC使用我们的测试工具(称为"Touchstone"(进行测试，该工具也是用C++编写。
我已经在Solaris 10(x86(上使用Oracle Solaris Studio 12.4(NOTGCC(以64位模式编译了这三个版本。
崩溃只发生在Touchstone以发布模式构建时，所以我花了相当多的时间在dbx中逐步完成组装，似乎发生了以下情况：
- "statement"对象的"this"指针存储在r14中
- 我们在驱动程序管理器(DM(中调用SQLColAttributes，它在驱动程序中调用SQLColAttributeW
- 在返回到DM之前，它将r14溢出到SQLColAttributeW的一个调用中的堆栈
- 在堆栈的另一端，抛出了一个异常(在离开驱动程序并返回DM之前，它最终被捕获(，在堆栈展开过程中似乎"一团糟"，所以一旦我最终返回到试金石，r14就是垃圾。Touchstone试图从语句对象中检索一个成员，并很快与SEGV崩溃
当我到达#3时，我做的第一件事是在寄存器溢出的堆栈上放一个硬件写表，但直到寄存器已经损坏，回到试金石后，它才会被击中。
然后我注意到似乎导致损坏的代码抛出了一个异常，并记住了这一点，我以前在使用solaris studio构建的Touchstone时遇到过，使用了gcc构建的驱动程序，所以我用solaris studio重新编译了iODBC，运行ldd不再显示对它的依赖，但它仍然以同样的方式崩溃。
我也尝试过那篇文章(LD_PRELOAD=/usr/sfw/lib/amd64/libgcc_s.so(中建议的变通方法，但这也没有改变任何东西。
我还能够编译valgrind，这似乎支持了我的假设：
-bash-4.1$ $VG --tool=memcheck $TC -te ApiTestEnv_utf32.xml -ts ApiTestSuite.xml -o crash -rts COLATTRIBUTETESTS

不幸的是，搜索_Uwn_jmp会出现这种情况(看看名称(，这意味着我看到了与我所认为的gcc/cc不兼容相同的情况。
同样的测试适用于32位。
有什么想法吗？
(不是完整的答案，但这似乎太长了，无法发表评论(。
TL:DR：检查ABI，而不是猜测哪个部分出错。
r14是SysV AMD64 ABI中保留调用的寄存器(不用于传递参数(。想要使用它的函数会在序言中推送它，并在后记中弹出它。但他们不在乎打电话的人用它做什么。他们只需要确保它在返回时和输入时具有相同的值。
进入catch条款时的寄存器状态似乎记录在ABI:的第6.2.6节中
将控制权转移到着陆台
在平台中执行代码之前，展开库会恢复寄存器没有被人格常规改变，使用上下文记录，以达到他们的状态引发异常的调用之前的帧，如下所示。指定的所有寄存器当由基本ABI保存的被调用者被恢复时，[并且
%rsi、%rdi、%rdx、%rcx用于传递关于异常的信息]。
ABI中最后一句话的最初结尾措辞混乱。我在[]里面的转述可能是错误的。(见该小节最后一段(。
基于本节和前几节(描述了如何调用每个帧的清理代码，即使它没有catch(，我几乎可以肯定，保留调用的寄存器会在catch中恢复。这与在展开过程中运行析构函数的机制相同，这是必要的。
因此，听起来错误是r14没有正确恢复。catch处理异常并尝试使用r14的函数没有做任何错误。
也许可以尝试在一些函数中包含析构函数，这些函数将在堆栈框架展开的情况下打印一些日志信息？也许让他们检查一个全局以决定是否打印，这样你就可以设置一个全局，然后进行会导致抛出异常的调用，这样你不会得到一个满屏的来自未抛出调用的日志消息。
如果您没有看到r14正在恢复，那么在展开的第二阶段，可能没有正确调用析构函数/清理。
在寄存器溢出的堆栈上放置硬件写入监视，但直到返回到试金石后才被命中
您应该使用读取观察点来查找在释放清理代码期间正在读取的溢出函数。在输入catch子句之前，没有任何内容覆盖溢出位置，这并不奇怪。
