> Could you elaborate?  i am sorry for top post, i hope this time the posting syle is ok. the scenario is as below:1. there is a APK(Android application package), the name of which is Roamsave, and this application will use libavcodec.so.2. i install this APK on a Samsung smart phone(ARM Cortex-A9-NEON), it runs well. it means the Roamsave can make a call.3. i install this APK on a Motorola smart phone(ARM Cortex-A9-NEON), it crashs in function ff_scalarproduct_int16_neon,     after disassembler libavcodec.so, i find that the crash reason is the second parameter of ff_scalarproduct_int16_neon does not    align to 128 bit, so ARM core give a data abort when executing un-alignment NEON instruction.   please advise, thanks very much.
