You can only have a single :: in an ipv6 address, so this was actually an invalid address. The bug fix (and bug report) is incorrect.

oups, I'm sorry, I think I missed my copy/paste.
with this : 
var_dump(filter_var('1fff:0:a88:85a3::172.31.128.1',FILTER_VALIDATE_IP,FILTER_FLAG_IPV6));
It doesn't work

My apologies for the previous error

funny thing is, var_dump(filter_var('1fff::a88:85a3::172.31.128.1', FILTER_VALIDATE_IP,FILTER_FLAG_IPV6));
returns 
string(28) "1fff::a88:85a3::172.31.128.1"
which is wrong

i.e. the implementation AS IS allows _two_ '::' in an ipv6 address
