Subject: [Bug libstdc++/106803] New: views::adjacent_transform should not return views::empty<tuple<>> when N == 0
Date: Thu, 01 Sep 2022 16:37:46 +0000 [thread overview]
Message-ID: <bug-106803-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106803
Bug ID: 106803
Summary: views::adjacent_transform should not return
views::empty<tuple<>> when N == 0
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: hewillk at gmail dot com
Target Milestone: ---
views::adjacent_transform seems to incorrectly copy-paste views::adjacent's
operator(), which makes it return views::empty<tuple<>> when N == 0, however,
according to the standard, it should return views::zip_transform(F) which is
views::empty<decay_t<invoke_result_t<FD&>>>.
