Well, actually the culprit here is neither the /bits nor the fun...
It's the $c! For example, the following variant of your code compiles
happily under HiPE:
fun (<< X, _/bits >>) when X =:= $c -> ok end.
I'll put it on my (long) TODO list but it's unlikely that this will be
fixed for R16B.
Merci beaucoup pour la rapport de bogue,
