Bug ID: 57730
Summary: class/struct mismatch for std::hash
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: d.frey at gmx dot de
When compiling with Clang and -Wall -Wextra -Werror, I get an error on a
mismatched declaration/definition for std::hash wrt the use of "class" vs.
"struct". The problem seems to be an inconsistent friend declaration in
/usr/include/c++/4.8/bits/stl_bvector.h
in line 523 (at least on my system, Ubuntu 12.04, GCC 4.8.1) where it reads
friend class hash;
and where it *should* read
friend struct hash;
which (for me) solves the problem.
There might be other places, I did a quick grep on "class hash" and found 4
occurrences in libstdc++, but I'm not sure how to find all cases or even how to
check for this.

Bug in clang to warn about this because they is perfectly valid standard C++
code.
