Smallbin double linked list corruption for specific data

[stevengj]

Not clear to me that this is a corruption in FFTW itself rather than a bug in xtensor.

@stevengj Wait! I changed my code as the following and the error still exists.

fstream fs_debug;
fs_debug.open("/home/winfred/l1b-pro/data/output/debug-8-7298.csv", ios::in);

vector<float> v_result;
string cell;
while (std::getline(fs_debug, cell, ','))
{
    v_result.push_back(stof(cell));
}
// This checks for a trailing comma with no data after it.
if (!fs_debug && cell.empty())
{
}

cout << v_result.size() << endl;    // 4096

vector<fftw_complex> result(v_result.size());
fftw_complex *in = reinterpret_cast<fftw_complex *>(fftw_malloc(sizeof(fftw_complex) * v_result.size()));

for (int i = 0; i < v_result.size(); ++i)
{
    in[i][0] = v_result[i];
    in[i][1] = 0.0;
}

fftw_complex *out = reinterpret_cast<fftw_complex *>(fftw_malloc(sizeof(fftw_complex) * v_result.size()));
fftw_plan plan = fftw_plan_dft_1d(v_result.size(), in, out, FFTW_FORWARD, FFTW_ESTIMATE);

fftw_execute(plan);

fftw_destroy_plan(plan);
