Using std::filesystem operations in a program built in the SDK results in odd/incorrect file permissions.
Please see this minimal test case:
As you can see, test.out has only w permission, no r permission when copied with
std::filesystem::copy
In SDK:
#include <filesystem>
int main(int argc, char *argv[])
{
std::filesystem::path src(argv[1]);
std::filesystem::path dst(argv[2]);
std::error_code ec;
std::filesystem::copy(src, dst, std::filesystem::copy_options::update_existing, ec);
}
