Lifehacker has a workaround.

Second, for whatever reason, this update causes erlang R12B2 to bus error at startup if you’ve enabled Hipe. Bummer. Workaround (courtesy of Geoff Cant): recompile from original source without hipe.

I don’t want an apache replacement, or at least have to bootstrap one just to write a webapp. I’d much rather have something very simple and callback based to handle requests and output dynamic data (and push static data through something else. No offense to erlang on that score but …)

for(Max, Max, F) -gt; [F(Max)];
for(I, Max, F) -gt; [F(I)|for(I+1, Max, F)].

My I suggest instead either:

lists:each(lists:seq(Min, Max), F).

or:


for(I, Max, F) when I <= Max ->
  for_impl(I, Max, F, []).
for_impl(Max, Max, F, Acc) ->
  lists:reverse(Acc);
for_impl(I, Max, F, Acc) ->
  for_impl(I+1, Max, F, [F(I)|Acc].

The original version of this code will blow out the stack with non-trivial length loops.
