Windows发行版中的std :: ifstream崩溃，退出代码为0xC0000409:未知软件异常 [英] std::ifstream crashes in release build on Windows with exit code 0xC0000409: Unknown software exception

问题描述

我正在使用 std :: ifstream :

printf("Before stream initialization\n");
ifstream stream(file_path, ios::binary);
printf("Stream initialized\n");
ifstream::pos_type position = stream.tellg();
auto file_size = position;
printf("Position acquired\n");

但是，该程序在二进制文件的释放模式下崩溃.这是已编译的汇编代码片段:

However, the program crashes in the release mode of the binary. Here is the compiled assembly code snippet:

在我的函数中，它在以下行崩溃:

In my function it crashes at this line:

.text:0000000000413504                 lea     rcx, [rdi+10h]

输出为:

Before stream initialization

Process finished with exit code -1073741819 (0xC0000409)

堆栈跟踪为:

std::locale::operator=(std::locale const&)
std::ios_base::_M_init()
std::basic_ios<char, std::char_traits<char> >::init(std::basic_streambuf<char, std::char_traits<char> >*)
MyExecutable::myFunction()

崩溃仅发生在 Windows 二进制文件中.该二进制文件适用于 Linux 的发布模式.我正在使用 MinGW 编译器来编译Windows二进制文件，并且编译标志为:

The crash only happens in the Windows binary. The binary works in release mode for Linux. I'm using the MinGW compiler to compile the Windows binary and the compilation flags are:

-fopenmp -O3 -DNDEBUG

它们是默认的 CMake 版本构建标记.我还确保传递的 file_path 是正确的.

They're the default CMake release build flags. I also made sure the passed file_path is correct.

有人知道出了什么问题以及如何解决吗?

Does anyone have an idea what went wrong and how to fix it?

推荐答案

这似乎是 MinGW 编译器错误，因为在 Visual Studio 中使用 MSVC 编译代码时，也不会发生相同的异常.

This seems to be a MinGW compiler bug since when using MSVC in Visual Studio to compile the code, the same exception does not occur either.
