From the elf(5) manpage in [[OpenBSD]]:

     .bss       This section holds uninitialized data that contributes to the
                program's memory image.  By definition, the system initializes
                the data with zeros when the program begins to run.  This sec-
                tion is of type SHT_NOBITS.  The attribute types are SHF_ALLOC
                and SHF_WRITE.
