使用 R 应用程序附件调试 .dll 会产生 "Illegal Instruction" 错误
Debugging .dll with R application attachment produces "Illegal Instruction" error
我正在调试的程序是一个 R GUI 应用程序，它利用多个 C .dll 文件来执行任务。我正在使用 Visual Studio 2019 作为我的调试器。
错误：Unhandled exception at 0x00000000279BB8CC (tcl86.dll) in rsession.exe: 0xC000001D: Illegal Instruction.
我不确定如何更深入地了解 tcl86.dll 为什么会这样。
这是我第一次调试程序，碰巧是一个相当复杂的程序，所以我不确定如何解释给出的输出。我会尽可能多地分享，如果我需要 post 更多信息，请告诉我。

这是调试器中的输出：alloc: invalid block: 000000002BF31390: 0 2bException thrown at 0x00000000279BB8CC (tcl86.dll) in rsession.exe: 0xC000001D: Illegal Instruction.
Unhandled exception at 0x00000000279BB8CC (tcl86.dll) in rsession.exe: 0xC000001D: Illegal Instruction.
这是调试器在 C 代码中停止的一些代码：
else if (strcmp(shape, "specimens") == 0)
{
specimen_del(0);
if (models != NULL)
{
Tcl_Free((char*)models);
models = NULL; //error symbol here
}
if (context != NULL)
{
Tcl_Free((char*)context);
context = NULL;
}
}
此 post 的目标是了解如何解释调试器提供的错误和信息以及我可能能够探索的潜在解决方案。谢谢！
该消息的第一部分 alloc: invalid block: 000000002BF31390: 0 2b 是来自 Tcl 库的消息。该消息的含义是内存已被越界内存写入损坏。该消息的生成位置在 Tcl 的线程感知内存分配器中，但 不是 错误所在的位置 是： 它正是检测到问题。
一旦内存损坏，所有关于程序未来行为的赌注都会落空；死于非法指令错误是完全可能的（这可能是由于堆栈损坏）。
如果内存未损坏，Tcl 和 Tk DLL（特别是堆栈跟踪中的 tcl86.dll 和 tk86.dll）都不会创建越界访问：我们确实会检查此类非常小心（并让开发人员构建模式，使任何此类问题出现，至少在它们的实现中）。但是，如果其他代码写在不应该写的地方（并且那里有很多我根本无法保证的代码）那么 所有赌注都关闭 因为正确性的先决条件代码不再有效。
tl;dr 您遇到了内存损坏问题。这很糟糕。
尝试使用诸如 electricfence 或 purify 之类的内存访问跟踪工具静态构建您的应用程序（可能还有其他工具，这并不是一个详尽的列表）；这样做对性能的影响是深远的，但它发现错误本身的可能性相当高。

这是调试器中的输出：alloc: invalid block: 000000002BF31390: 0 2bException thrown at 0x00000000279BB8CC (tcl86.dll) in rsession.exe: 0xC000001D: Illegal Instruction.
Unhandled exception at 0x00000000279BB8CC (tcl86.dll) in rsession.exe: 0xC000001D: Illegal Instruction.
这是调试器在 C 代码中停止的一些代码：
else if (strcmp(shape, "specimens") == 0)
{
specimen_del(0);
if (models != NULL)
{
Tcl_Free((char*)models);
models = NULL; //error symbol here
}
if (context != NULL)
{
Tcl_Free((char*)context);
context = NULL;
}
}
此 post 的目标是了解如何解释调试器提供的错误和信息以及我可能能够探索的潜在解决方案。谢谢！
该消息的第一部分 alloc: invalid block: 000000002BF31390: 0 2b 是来自 Tcl 库的消息。该消息的含义是内存已被越界内存写入损坏。该消息的生成位置在 Tcl 的线程感知内存分配器中，但 不是 错误所在的位置 是： 它正是检测到问题。
一旦内存损坏，所有关于程序未来行为的赌注都会落空；死于非法指令错误是完全可能的（这可能是由于堆栈损坏）。
如果内存未损坏，Tcl 和 Tk DLL（特别是堆栈跟踪中的 tcl86.dll 和 tk86.dll）都不会创建越界访问：我们确实会检查此类非常小心（并让开发人员构建模式，使任何此类问题出现，至少在它们的实现中）。但是，如果其他代码写在不应该写的地方（并且那里有很多我根本无法保证的代码）那么 所有赌注都关闭 因为正确性的先决条件代码不再有效。
tl;dr 您遇到了内存损坏问题。这很糟糕。
尝试使用诸如 electricfence 或 purify 之类的内存访问跟踪工具静态构建您的应用程序（可能还有其他工具，这并不是一个详尽的列表）；这样做对性能的影响是深远的，但它发现错误本身的可能性相当高。
