I tried this on locally compiled R9C-1 and R9C-2 running on Debian
unstable. No problem in either case:

  | Erlang (BEAM) emulator version 5.3.6.3 [source] [hipe]
  | 
  | Eshell V5.3.6.3  (abort with ^G)
  | 1> c(loop1).
  | {ok,loop1}
  | 2> fprof:apply(loop1, l, [10]).
  | 10

Maybe it's some random memory trashing, maybe it's a toolchain
problem. I don't have any SuSE machines, but someone else on the list
is bound to.
