The submitter of this bug eventually reported back (there was a
problem with his email address) and tested the updated package (with
your patch); unfortunately it seems that the patch did not improve the
output very much :-( He wrote:
----------------------------------------------------
Started by /etc/init.d/postgresql:
2004-06-07 14:24:59 [6455] LOG: authentication file token too long, skipping: "(garbage)"
I piped the garbage through xxd and got:
986e 0241 9131 f840
I ran it again from the command line, as user postgres and got, instead:
98e3 ed40 9101 e340
These garbage strings are repeatable.
In either case, I did get the seg fault.
----------------------------------------------------
Does that say anything to anybody?
Thanks and have a nice day!
Martin
