I don't have any specific knowledge of any particular software. My
information is based on having read a paper or two on the subject
several years ago.

I suggest you try Google and see what pops up.

However, my point is that even if you try writing something, it will
either crash the machine very quickly, or have to be so careful not to
destroy important data structures, that it won't usefully test
anything. eCos is simply not fault tolerant in the way you seem to
want to test.
