Comment 1 Warren Togami 2004-10-30 23:21:22 UTC
Confirmed.  Perhaps it is something in about the arbitrary data coming
from the whois over the network?  *bad*

No, it happens when there is more than one redirection. This patch quiets down
valgrind on FC2, I'll test on FC3t* tomorrow.

Comment 4 Dams 2004-10-31 00:47:25 UTC
Miloslav : tested on fc3t3/rawhide : 

[anvil@gruyere ~]# LC_ALL=en_US.UTF-8 whois
[Querying whois.arin.net]

OrgName:    Asia Pacific Network Information Centre
OrgID:      APNIC
Address:    PO Box 2131

Sounds good. Thanks.

Comment 5 Miloslav Trmač 2004-10-31 23:30:21 UTC
Dams, thanks for testing.
Built for rawhide; fixing in FC3 will probably have to be done
in an update.

Comment 6 Miloslav Trmač 2004-11-10 19:22:29 UTC
Fixed in jwhois-3.2.2-6.FC3.1. Thanks.
