我在用
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,程序在二进制文件的释放模式下崩溃。下面是编译的程序集代码段:

在我的函数中,它在这一行崩溃:
.text:0000000000413504 lea rcx, [rdi+10h]
输出为:
Before stream initialization
Process finished with exit code -1073741819 (0xC0000409)
stacktrace是:
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()
车祸只发生在
Windows
二元的。二进制文件以释放模式工作
Linux
. 我用的是
MinGW
编译Windows二进制文件的编译器和编译标志是:
-fopenmp -O3 -DNDEBUG
他们是默认的
CMake
释放生成标志。我也确保通过了
file_path
是正确的。
gdb

有人知道哪里出了问题,怎么解决吗?
