[erlang-bugs] R16: HiPE failure with /bits in funs

[Loïc Hoguin]

The following module fails to compile with R16. It also fails on R15B03 
and probably previous versions. I do not know HiPE internals so no patch.


-module(hipe_error).
-export([run/0]).

run() ->
	fun (<< $c, _/bits >>) -> ok end.


The following errors are reported:
