I quess the point is that at least the knowledge of the bugs the 
compiler has does not get old. If you always use the newest 
version of GCC for instance, there is the possibility that code 
changes due to new features or refactoring have caused new bugs 
since the bug manifestation site was last tested.

Still, one would think it'd be more efficient to certify a 
version of an open-source compiler from a public interest fund, 
and anyone could then use that version for free.
