-DCMAKE_BUILD_TYPE=Release does not use -fno-strict-aliasing while -DCMAKE_BUILD_TYPE=RelWithDebInfo does use it which explains why I saw the warnings but others might now.

Hi Mark,

We only support and test "RelWithDebInfo" and "Debug". Documented here:
http://dev.mysql.com/doc/refman/5.6/en/source-configuration-options.html#option_cmake_cmak...

Do you still get any errors with either two of these?

Should we consider this bug report a feature request to add support for "Release"?
[10 Dec 2015 17:15] Mark Callaghan 
Yes, consider this a request to support Release or remove support for it.

Fixed in 8.0.13.

The CMAKE_BUILD_TYPE CMake option now supports a Release build type,
which is like the RelWithDebInfo build type but omits debugging
information to reduce the build size.
