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.
