It's the zext to a really weird type. Generally static initializers
are only supported if they map neatly to a target's relocation (or an
expression not needing any relocation).

You could probably emulate it with something (depending on endianness) like

    @var = global [i32*, i8] [i32* @an_integer, i8 0]

cast that to an i72* before each use and you probably can't tell the difference.
