Have a look: https://gist.github.com/uecasm/b547db812ae4bba39bb1bd0443801507 (I marked it as secret just so that people don't stumble across it without the context; I don't mind it being used.) I'm not 100% certain I have the allocator_traits officially correct (and I've omitted some constructors that would be required for stateful allocators that require initialisation), but it seems to work as expected. With BOOST_NO_EXCEPTIONS defined the noexcept vs. except implementations end up being largely identical, although it will still exercise both paths depending on the declared types. Didn't seem worthwhile chasing the tiny size optimisation that could potentially result from being aware of this. A sufficiently clever compiler might do it itself, although it would surprise me. Similarly mpmc_fixed_bounded_value could avoid the heap allocation if written differently, but sometimes that's not a good thing. -- --- You received this message because you are subscribed to the Google Groups "Scalable Synchronization Algorithms" group.
