[Csnd] LPC random bursts [bug?]

Hello,

I'm trying to use lpread and lpreson opcodes, having analysed a short  
vocal [test] sound with lpanal. However I get nasty explosions during  
the re-synthesis, like bursts of feedback which is I think the filters  
blowing up. I assume the distortions are in the analysis data, I used  
the default settings for analysis but still I don't think this should  
be happening.

Please please be very careful with the below csd & analysis file  
attached. Do NOT test it with headphones, and turn your volume down  
all the way, the bursts are unbearably loud!!

Any advice would be great.

Thanks in advance

Peiman

P.S. As far as I remember I never managed to actually use LPC, every  
time there was a different problem :-)
