Sorry. I was trying with trunk, not 5.3. I can now reproduce this on
5.3 (but not trunk) on the Apache SAPI (but not with FastCGI).

Works here:
Script: var_dump(fsockopen("localhost", 9876));
ncat -4 -k -l 9876 -v -v
15:22:42,3106124 httpd.exe 2504 TCP Reconnect
0:0:0:0:0:0:0:1:6660 ->
0:0:0:0:0:0:0:1:9876 SUCCESS Length: 0, seqnum: 0, connid: 0
15:22:42,8106355 httpd.exe 2504 TCP Reconnect
0:0:0:0:0:0:0:1:6660 ->
0:0:0:0:0:0:0:1:9876 SUCCESS Length: 0, seqnum: 0, connid: 0
15:22:42,8210523 httpd.exe 2504 TCP Connect 127.0.0.1:6661
->
127.0.0.1:9876 SUCCESS Length: 0, mss: 1460, sackopt: 1, tsopt: 0,
wsopt: 1, rcvwin: 8192, rcvwinscale: 8, sndwinscale: 8, seqnum: 0,
connid: 0
15:22:42,8216731 httpd.exe 2504 TCP Disconnect 127.0.0.1:6661
->
127.0.0.1:9876 SUCCESS Length: 0, seqnum: 0, connid: 0
So tries IPv6, fails, then tries IPv4.
Now with a process listening on IPv6:
ncat -6 -k -l 9876 -v -v
15:25:44,6140323 httpd.exe 2504 TCP Accept
0:0:0:0:0:0:0:1:6672 ->
0:0:0:0:0:0:0:1:9876 SUCCESS Length: 0, mss: 1440, sackopt: 1, tsopt: 0,
wsopt: 1, rcvwin: 8192, rcvwinscale: 8, sndwinscale: 8, seqnum: 0,
connid: 0
15:25:44,6238583 httpd.exe 2504 TCP Disconnect
0:0:0:0:0:0:0:1:6672 ->
0:0:0:0:0:0:0:1:9876 SUCCESS Length: 0, seqnum: 0, connid: 0
Tries with IPv6 and works the first time.
As expected. The only normal case when "127.0.0.1" would work but not
localhost with a service listening only with IPv4 is if the packet for
the initial attempt with IPv6 would get dropped instead of the OS
getting a RST packet back rejecting the connection.

127.0.0.1 works
localhost doesn't

And please try it.... that's what has been asked. Asking Gustavo to test
again is
good but in the end, we like to know that you don't see the problem
anymore.

Does your example that both 127.0.0.1 and localhost work when only IPv4
is used?
