Boost C++ Libraries: Ticket #11286: Code in boost/endian/buffers.hpp violates old C++03 Standard

Sergey.Sprogis@… — Mon, 11 May 2015 21:33:15 GMT

After filing this ticket I realized that I was not quite right about header itself.

Actually boost/endian/buffers.hpp code is good, because it only contains

endian_buffer & operator=(T val)

but the real issue is inside libs/endian/test/endian_in_union_test.cpp test itself which contains 'union U' Based on this, the fix should be pretty easy: just to put all those unions under some NO_CXX11 macro. Only I'm not sure which one is currently most suitable for that kind of differences. May be a new one should created?

This is not a bug in endian_in_union_test.cpp.

This is a error caused by a bug in an older version of the compiler. It confused user-defined assignment with user-defined copy assignment, which is what is actually prohibited. This was a bug in some older versions of GCC that has since been fixed.

The test passes for modern gcc, clang, and msvc compilers in -std=c++03 mode.
