Description:
When lauching the following script, it occurs that :
--------------------------------
data=00000000 00000 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
data=abcd
data=efghi
3
--------------------------------
My system is a debian 3.1. The script was correctly running before (maybe en
update
of bash ?)
mplayer (which is involved in the bug), is in the following version :

Here is the script :
