Why does an error occur at the end of a file that ends with whitespace in a while loop, using the read operator?

I want to execute a read function from a "material" vector (I created this type with "struct"). The reading will be executed from a file.

std::vector<material> material_read(std::string s)
{
    std::ifstream data(s);
    dados.exceptions(std::ios::failbit |
            std::ios::badbit);

    std::vector<material> infomaterials;
    material mat_read;

    while (data >> mat_read.idmaterial) {
        data >> mat_read.idmaterial;
        data >> mat_read.rho;
        data >> mat_read.pricekg;
        infomaterials.push_back(mat_read);
    }

    return infomaterials;
}

The file I should read (and I can not make changes) is as follows, with spaces after all lines:

1   1.02    82.76   
2   2.81    29.45   
3   1.46    14.41   
4   1.15    31.54   
5   1.04    71.10   
6   1.11    87.05   
7   2.84    13.81   
8   1.56    27.55   
9   2.63    71.30   
10  0.87    25.59   
11  2.99    24.83   

I think reading each number on each line is going well. However, there is an error in the execution, when it reaches the end of the file:

  

terminate called after throwing an instance of   'std :: ios_base :: failure [abi: cxx11]' what (): basic_ios :: clear:   iostream error Aborted (recorded core image)

I tested by printing something on the screen before and after each read operation. It really does all 33 readings I expected. But after reading the 33rd value, it does not even enter the while loop again, and then it shows the error.

It is possible that, as the data > > mat_read.idmaterial failed, give me the error message? Is this happening because the file ends with spaces?
