Remove the workaround for the gcc bug 51626?

[Chandlerooo]

I notice there is a workaround:
https://github.com/gentryx/libflatarray/blob/master/include/libflatarray/aligned_allocator.hpp

    /**
     * Added due to compiling for Intel MIC with CPP14=TRUE
     * GCC Bug Report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51626
     */
    void construct(pointer p)
    {
        std::allocator<T>().construct(p, value_type());
    }

This compiler bug is marked as fixed: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51626
Shall the workaround be removed? Is the compiler bug actually fixed?
