Short summary of the problem can be seen in link :


In the code below when float[] amplitudeByTime is more than 1660 I am getting a
exception from writeln function. If the size of this array less than 1660(which
I can determine with global variable"static const int total_data_size") no
exception occurs. 

Exception : 
std.stdio.StdioException std\stdio.d(2431): Bad file descriptor

main.d : 
import std.stdio;
import std.numeric;
import std.file;
import std.algorithm;
import std.array;
import std.conv;
import std.string;

static const int total_data_size = 1661 ;//131072; //2^16
static const int sampling_frequency = 44100;

auto file2string(string filepath) 
{
      char[] buf;
      // line;
      int line_counter = 0;
      string input;
      try
      {
          input = cast(string)std.file.read(filepath);
      }
      catch (Exception e)
      {
        writeln(e); 
      }

      int count = 0;
      foreach (line; input.splitter("\n"))
      {
            line = chomp(line);
             if (isNumeric(line))
             {
                   count++;
                   if (count == total_data_size)
                {
                      buf ~= line;
                    break;
                }
                buf ~= (line ~ " ");
          }
      }

      return to!(float[])(split(buf));

}



void main()
{ 
    char[] buff;
    auto amplitudeByTime =
file2string("C:/Users/USER/expTreeTry/spectogram/src/sample-data8.txt");
    writeln(amplitudeByTime);



    char[] read;
    readln(read);
}
