I wrote a PostScript prolog called "multi.ps". It's purpose
is to put multiple "logical" pages onto a physical page(ie two a5
pages side by side on a a4 page). It works by overloading all the
operators which affect the absolute graphics state with procedures
which go back to the normal state, do their "thing" and convert back.
Part of the "conversion" is mapping paths and clippaths - this uses
pathforall. Someone has given me a PostScript file which, when
multi.ps is prepended, gives an "undefinedresult" for operator "pathforall"

What conditions can make this happen?

Thanks
