This is not so theoretical. This is required, for instance, for amd64. Because
compiler by default generates so called small code model where text and data
of object shall live in lower 2 Gb of address space. Solaris linker will give
warnings when relocations are to big to fit into signed 32-bit location. Our
linker will silently ignore overflow. This will result in either core dump
(if you lucky), or data corruption.
