Comment 2 for bug 485574

Hi (I'm a french guy, so sorry for my english :-( )

I think I have a similar problem ....under ubuntu 9.10 and mawk 1.3.3
I write a program to check a log file (connexion POP / IMAP).
The input file was previously sort session by session (field 4, FS = :)

I found some case where my program don't detect all new/other session when I use mawk
So I decide to test my program with gawk (3.1.6) , and then it's OK

You will find below my program (only the essentiel lines), a file for testing (15 lines), and command and results for mawk and gawk

I think my program is correct, so ... May it help
-------------------------
#!awk
BEGIN {
FS=":";
savtoken="";
}
#
{
token=$4;
if (savtoken!=token)
  printf ("new session %s / %s\n", savtoken, token);
else
  printf ("same %s / %s\n", savtoken, token);
savtoken=token;
}
-----------------------
