I'm using CVS compiled version of 2004-01-21 10:00 GMT+1 and I'm 
experimenting the following problem with pipe !

 From a bash script I'm running the following command (after a lot of 
other's) and bash crash.
The first command is a win32 application isql (Sql server 2000 tool), 
and other are sed and sort from cygwin.
If I put these commands in a little script, no problem. Before no 
problem at all, but now the first command returns 3'768'666 bytes (a 
little bit more).
