Yes. This is generic. It happens on all platforms I've tested.

I've no idea what you have in mind.  As far as the HiPE compiler is 
concerned, this is the first bug I recall in a long while. In fact, this 
particular one aside, there are no outstanding bugs I know of -- which 
of course does not preclude the existence of bugs I know nothing about.

In any case, to answer your question, I am not aware of any good reasons 
for somebody to prefer R11 over R12 as far as HiPE is concerned.

I'm willing to bet the situation is similar for BEAM: most (if not all) 
R11 compiler bugs have been fixed in R12 and the Erlang/OTP team has 
been *very* responsive in correcting and publishing patches for all R12 
compiler problems that have been reported in this list.
