Comment:

 Hi! Thanks for this bug report.

 Tor documents that IPv6 address syntax that is does support:
 [xxxx::xxxx:xxxx].

 It does not support additional IPv6 syntax, including specifying
 interfaces using the % syntax.

 The parsing of these kinds of addresses also looks like a bug - it should
 not parse ` fe80::1` as a separate part of the address:
 {{{
 Oct 10 21:34:28.386 [warn] Could not bind to
 fe80::1[c9a:c3ff:fec8:7768:9040 c9a:c3ff:fec8:7768:9040]: Invalid argument
 }}}
