Dear Speex Devs,

One more problem from my side. I had earlier queried about bad quality of
speex.

For this run, I changed the memory mode option in CCStudio to none from
large. (I will explain this if required.)
Now, I am trying to run speex on C55x in real time.

Find a code snippet from my main function below.

Basically, I am getting the error mentioned in the subject line.
Weird thing is that, for the statements marked in bold below, if I enable
printf, I don't get this error, whereas if I disable it, Speex complains
with this error.
Is it because of the delay required?

By having a look at the code, and the code structure which I have mentioned
in the code itself, can you throw some insight?
Also why should this error occur at first place? I searched the forum but
could not find the exact solution.

Awaiting reply.

Vijay
