#95 multithreading error

[Yunpeng Men]

Hey, I found there seems a bug in LoadToFilN.C, which can lead to multithreading error. After I revised it, it worked. My command line is "digifil tmp1.fil -b 8 -threads 4 -o tmp2.fil"

dsp::LoadToFil* dsp::LoadToFilN::new_thread ()
{

• return new LoadToFil;
• return new LoadToFil(configuration);
  }
