Vinnie, thanks for giving this a try!

The build completed successfully but with warnings (see attached text file). The warnings seem benign with these exceptions:

d:\lib\boost_1_61_0\boost\graph\named_function_params.hpp(240) : warning C4172: returning address of local variable or temporary

Yep, sounds scary, but this line appears to be from 2012, so probably not a release blocker. Can anybody looks at this after release?

I'd guess we can pass on this as well, given that Boost.Signals is deprecated. Thanks again, -- Vladimir Prus http://vladimirprus.com

I have verified that the hashes of the downloaded libraries (and the one I built the windows binaries from) match those in the above message. However, I was unable to verify that they were correctly signed, as the attached signature file didn't contain the hashes. Also, once the files are renamed for the release, the hashing script should be re-run so that the correct filenames (without the _rc2) are listed for the file hashes (the actual hashes should be the same as whatever rc* is eventually released).

New subject: lockfree workaround for msvc compiler bug (was Re: Boost 1.61.0 Release Candidate 2)

...

The second release candidates for the 1.61.0 release are now available at:

might be too late for 1.61, but since msvc's update fixed one compiler bug by introducing another, boost.lockfree won't compile with the latest msvc update. the least intrusive change i could come up with is the following: https://github.com/boostorg/lockfree/commit/547f131cb0034ea9d8fe5de33911730c... it doesn't introduce any functional change, but gives users the possibility to force the use of boost::atomic instead of relying on std::atomic by defining the BOOST_LOCKFREE_FORCE_BOOST_ATOMIC macro. is it ok to merge this into master before 1.61 comes out? we could add a release note: -- Due to a bug in VS 2015 Update 2 boost.lockfree might trigger error C2338. The suggested workaround is to define BOOST_LOCKFREE_FORCE_BOOST_ATOMIC. -- cheers, tim

The behavior contradicts the standard and therefore is a bug. The intention doesn't matter.

* msvc had a bug * boost.lockfree didn't trigger the bug * msvc fixed the bug, rejecting valid code which didn't trigger a bug * from the point of view of boost.lockfree this is a regression - -- it is perfectly fine to introduce one bug (even a regression) on purpose in order to fix another. i can absolutely understand the rationale behind it. however the wording that "This is not a bug" and "If this has already been fixed in 1.61.0, then that's great" is unprofessional: it implies that the behavior is standard-compliant and that the user code (boost.lockfree) contains a bug, while in truth boost.lockfree would have to work around a compiler bug. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJXM3dBAAoJEAIkvWiom07DE0EP+wYPfJGwIDUAkn1sT44ZSqCb 6HKRev1I7zpBFmYuP8QDaMb5w22e9tvQeu/NQyxjsc8G+5viRRofyC876CKPCulc q8e8SURZJPDSX4GivTw2Tjgqnaa6XJXVqKSJv1otv/4clWGuIKpTgki1N5IhOwjS eSzZwKV20GAdLbMBjPwncMVL9urkZVN0sAqqF5Fp3VDAUN3m/bbfqDWMh1PRAZfZ 0WB7Rt9gXFaPQm73qCyDSIwB+X2PawBuxDneXmLP3L9oEdPrRxuVHE6AAA/YshtI Ssewh1kut7U6+hxgdI+nUTWC1nWsvAc14g643GBO9Xtgzs3/tSllVtylJnXfFv/U MOp29pVLfzglkMvZvBoraqpH9HiEv1OSP4PfUT+bBdoeazf3/y2Qhec8zXwq/T5v ur+qT7iwncqD4qs2a4uXORfEE7GegTFWbVDRstgqq9zGqGcpdM9ZY/8egkegFcDT K1Cgsa/Jm8vYMQX9Fb7yJb2OyR5/mSE8ZmOhnGwCMEgIo2jukB06vVsVQBTcssCc thPLhp0BErVqytH49IGLC0zGa1dTQ+3ziRwSf74lwQ9r9vL7/fUNAEW/r2RU2/OI IJahMj138ntr7bpU5VkNpFcV1cLOR/C5XtA0MDcIgBkHqZORVh19QuK8Fn8hDIlW 8FALeaj1Qohs6okCTF6Q =3Duz -----END PGP SIGNATURE-----
