Hello! The patch to fix the Zero builds on SPARC has been updated again after some discussion upstream where we learned that memset_with_concurrent_readers must always use the SPARC-specific implementation as the glibc implementation of memset can cause problems with concurrent threads may see zeros temporarily in memory being copied due to the block-initialize store instructions used in memset. The attached patch therefore uses memset_with_concurrent_readers_sparc.cpp also for Zero builds. I also included a patch header this time which points to the upstream bug report and merge status. Thanks, Adrian -- .''`.
