It probably wouldn't be too hard, considering the fact that they
already can instrument object code on Windows NT / x86.
Well, at least, not impossible...
Purify inserts their own instructions into your program's object code
(on Unix systems, at *link time*). Purify basically knows about every
load and store that your program makes into main memory, and from this
knowledge it can detect memory problems.
This is a neat trick, and in practice, it yields good results.
