A buffer's size cannot be larger than some maximum, which is defined
by the largest buffer position representable by the @dfn{Emacs
integer} data type. This is because Emacs tracks buffer positions
using that data type. For most machines, the maximum buffer size
using that data type. For 64-bit machines, the maximum buffer size
enforced by the data types is @math{2^61 - 2} bytes, or about 2 EiB.
For most 32-bit machines, the maximum is @math{2^31 - 1} bytes, or about 2 GiB.
For some older machines, the maximum is @math{2^29 - 2} bytes, or
about 512 MiB. Buffer sizes are also limited by the size of Emacs's
virtual memory.
