The algorithm currently used for minimizing the size

(See CACM article) might generate assertion failures if

any displacement it is trying to minimize increases during

the assembly process. The only way to avoid increases

like that is to fix the sizes of all displacements in

non-text segments.

might detect in the first pass (0) whether the value
|

|
of the expression depends on any symbols whose value
|

|
might alter later on in the assembly process. In that case

one could determine the right size in the first pass in

most cases.
