Build fails: `error: no matching function for call to 'get_rounded_size(const unsigned int:30&, const std::size_t&)'`

Reproduce the failure with the shown R CMD INSTALL invocation, then inspect ipcmutex.cpp and the referenced BH headers: boost/interprocess/detail/segment_manager_helper.hpp and utilities.hpp. Determine whether the incompatible argument types originate in BiocParallel or its BH/Boost dependency; done means a confirmed package-side resolution or a documented upstream report and reference.

Or is this a bug in Boost, and I should open an issue with their upstream instead?
