+%%--------------------------------------------------------------------------
+%% Program which resulted in a badarg crash when compiled to native code.
+%% The problem was that hipe_icode_primops was stating that the primop
+%% {bs_start_match, ok_matchstate} could not fail which made the icode_type
+%% pass removing the third clause of flatb/1.
+%%
+%% (The program was working correctly with hipe option 'no_icode_type'.)
+%%
+%% Reported by Andreas Sandberg on 3/1/2011 and fixed by Kostis on 5/1/2011
+%% with the help of Per Gustafsson.
