For the record, in this particular case there was no bug in HiPE.

For better or worse, the HiPE compiler relies on certain invariants in 
the code that the BEAM compiler generates.  Whenever these invariants 
get broken, perhaps for very good reasons as in this case, the HiPE 
compiler also needs to be adapted to not rely on them anymore.  It's a 
quite natural process in software components that depend on each other 
that would not classify as a bug.
