[Bug libstdc++/56627] New: class hash instead of struct hash
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56627 Bug #: 56627 Summary: class hash instead of struct hash Classification: Unclassified Product: gcc Version: 4.8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: andreas.hans...@gmail.com In the gcc 4.8.0 c++ standard library headers, bitset and bits/stl_bvector.h both incorrectly use class instead of struct for the hash function. For example, bits/stl_bvector.h: #if __cplusplus >= 201103L template friend class hash; #endif class should be struct

Technically the code is ok, and in line with the language standard. However, as at least one of the most popular compilers (clang 3.2 RELEASE with -Wall) issues a warning for this. Thus, it might be worthwhile fixing.

Not a > bug, not worth wasting time on. The potential for "real problems" was my main reason for pointing it out. I ran some (unrelated) tests on Fedora Rawhide (fc19) with clang 3.2 RELEASE and gcc 4.8.0 and this issue popped up as -Wall -Werror was used for the project in question. The two lines mentioned are the only issues encountered. If it is worth "fixing" or not I leave up to you to decide, I merely wanted to highlight the potential issues.
