I get core.exception.InvalidMemoryOperationError@(0) when I run the following program on attached input file (XML).


import std.algorithm, std.file, std.stdio, std.string;

int main(string[] args)
{
  if (args.length < 2) {
    return 1;
  }

  size_t linect = 0;
  foreach (line; File(args[1]).byLine())
    linect += 1;

  return 0;
}

Backtrace:
