after test current FFmpeg git head, crash still occur

Do you see the same crash when compiling for 32bit arm?

Thanks for your help
The crash only happen in 32bit arm
Maybe this is a configuration issue, I will check it more
in 32bit arm platform, the address of ff_msmp4_mb_i_vlc symbol is 0xf5773638, this is fault
My 32bit arm configure line is below:
--arch=arm --target-os=linux --enable-cross-compile --cross-prefix=/home/workspace/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin/../../../arm/arm-linux-androideabi-4.8/bin/arm-linux-androideabi- --sysroot=/home/workspace/prebuilts/ndk/current/platforms/android-21/arch-arm --enable-shared --enable-gpl --disable-avdevice --disable-ffserver --disable-postproc --disable-ffplay --disable-static --enable-yasm --enable-asm --disable-avresample

ffmpeg compile configuration issue
