Description Marcus Meissner 2021-01-18 09:53:13 UTC 
In x/text in Go 1.15.4, a "slice bounds out of range" panic occurs in language.ParseAcceptLanguage while processing a BCP 47 tag. x/text/language is supposed to be able to parse an HTTP Accept-Language header.

This issue is not directly about go, but about golang-org-x-text
