Below is a complete piece of code that still exhibits this
issue. The file "data_random.dat" simply contains a single
row of random ints (about 30M filesize). Each iteration
allocated additional heap and I don't seem to be able to
free foo no matter what.

import std.stream;
import std.stdio;
import std.contracts;
import std.gc;


double[][] parse(BufferedFile inputFile)
{

  double[][] array;
  foreach(char[] line; inputFile)
  {
    double[] temp;

    foreach(string item; std.string.split(assumeUnique(line)))
    {
       temp ~= std.string.atof(item);
    }

    array ~= temp;
  }

  /* rewind for next round */
  inputFile.seekSet(0);

  return array;
}



int main()
{
  BufferedFile inputFile = new BufferedFile("data_random.dat");

  while(1)
  {
    double[][] foo = parse(inputFile);
  }

  return 1;
}
