I've reduced the incorrect code to this:

-module(foomod).
-export([handle_info/2]).
-record(state, { foo = undefined }).

handle_info({_}, State) ->
   foo(),
   State#state{foo = bar},
   case ok of
   _ ->
     case catch foo() of
     ok ->
       {stop, State}
     end
   end;

handle_info(_, State) ->
   (catch begin
     foo(),
     State#state{foo = bar}
   end),
   case ok of
   _ ->
     case catch foo() of
     ok ->
       {stop, State}
     end
   end.

foo() -> ok.
