... I expected that we would find some flaws in CompCert’s
formalisms. My meager experience in formal specification is that getting
a large specification right is heroically difficult — perhaps not much
easier than getting a complicated software system right in the first
place. So far, however, we have found no errors in the CompCert PowerPC
specification, their C-light specification, or in their proof
strategy. This is pretty amazing and my opinion of the job done by the
CompCert team is astronomically high.
It's an old article but they did in fact find some CompCert bugs back then.
