In the 12+ years I've been a professional developer, I can only remember two bugs that were caused by the compiler / interpreter, everything else were logic bugs, oversights, 3rd-party libraries, misunderstanding of the requirements, internal contradictions in the requirements etc.

So that's maybe 0.1% of all the bugs I've touched.

In that sense, code generation isn't really an interesting source of bugs for the discussion at hand.

There were more ~26+ years ago. gcc and egcs had some subtle register allocator bugs that would get tripped up under heavy register pressure on i386 that were the bane of my existence as a kernel developer at the time.
