I'm reading a file using std::ifstream:
printf("Before stream initialization
");
ifstream stream(file_path, ios::binary);
printf("Stream initialized
");
ifstream::pos_type position = stream.tellg();
auto file_size = position;
printf("Position acquired
");
However, the program crashes in the release mode of the binary. Here is the compiled assembly code snippet:

In my function it crashes at this line:
.text:0000000000413504 lea rcx, [rdi+10h]
The output is:
Before stream initialization
Process finished with exit code -1073741819 (0xC0000409)
The stacktrace is:
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()
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
They're the default CMake release build flags. I also made sure the passed file_path is correct.
gdb says:
