Obviously you're unfamiliar with Ken Thompson's self-reproducing
backdoor in login, which was inserted via a hack introduced into GCC--a
hack that also introduced *itself* into GCC when GCC was used to
self-compile.
http://www.acm.org/classics/sep95/
The beauty of Ken's hack was it only needed to be inserted once, after
which all traces of the hack could be removed from the source. The hack
reproduced solely in the object code.
You'd also do well to review the 1974 paper on Multics security that
gave Ken the idea in the first place:
