I haven't been able to reproduce the problem. Can you send either an
audio file that reproduces the problem with speexenc or a simplified bit
of source code that I can use? So far, I have one potential (but
unlikely) explanation: in the file ltp.c, line 83, you have:

for (i=0;i<N;i++)
{
     best_score[i]=-1;
     gain[i]=0;
}

can you change that to:

for (i=0;i<N;i++)
{
     best_score[i]=-1e10;
     gain[i]=0;
     pitch[i]=0;
}

and see if it works?
