[[
While c is an ASCII digit, set value to value × 10 + c interpreted as decimal number and increase pointer by one. 
]]

Should this be limited to three digits, or is this valid? http://[::127.0.0.00000001]/

In fact, is any non-significant zero prefix allowed?
Comment 1 Anne 2013-12-04 15:00:18 UTC 
Per the URI RFC it is not allowed. In fact, that only allows

0-9 or
1-9 followed by 0-9 or
1 followed by 0-9 followed by 0-9 or
2 followed by 0-4 followed by 0-9 or
2 followed by 5 followed by 0-5

which seems to be what Gecko does although not what their code suggests :/
