--- Comment #3 from Ian Hamilton <ian at g0tcd dot com> --- Just a thought. Does ((int)(sizeof(NSQ_del_dec_struct) / sizeof(opus_int32)) correctly give you the size of the sLPC_Q14 array? >From playing with my test case, it seems that if the optimiser spots that k will go beyond the end of your array, it doesn't bother checking it each time round the loop, hence an infinte loop. Seems that gcc 4.8's aggressive loop optimiser also gives up aggressively when presented with invalid code.
