Description Marcus Meissner 2021-01-18 10:19:15 UTC
In x/text in Go 1.15.4, an "index out of range" panic occurs in language.ParseAcceptLanguage while parsing the -u- extension. x/text/language is supposed to be able to parse an HTTP Accept-Language header.

It looks like this issue is not directly about go, but about golang-org-x-text.

@Jeff, please verify.
