11208,Swapping allocators does not use ADL,Alex Merry <alexander.merry@…>,Jan Gaspar,"boost::circular buffer has issues when using it with Boost.Interprocess, due to attempting to use std::swap on the allocators. Specifically:

{{{#!cpp
void swap_allocator(circular_buffer<T, Alloc>& cb, const false_type&) {
    std::swap(m_alloc, cb.m_alloc);
}
}}}

does not allow ADL to find the correct swap implementation. This can be worked around by specializing std::swap, but this is not ideal, and leads to some compile issues on OSX with Clang.

The correct implementation would look like

{{{#!cpp
void swap_allocator(circular_buffer<T, Alloc>& cb, const false_type&) {
    using std::swap;
    swap(m_alloc, cb.m_alloc);
}
}}}",Bugs,new,Boost 1.59.0,circular_buffer,Boost 1.58.0,Problem,,,
