Hi,
I'm using snpe-1.35.0.698 now and model data is inception_v3 which is downloaded by using "python $SNPE_ROOT/models/inception_v3/scripts/setup_inceptionv3.py -a ~/tmpdir -d " for CPU.
I got a problem as below while execute snpe-sample which is compiled with x86_64-linux-clang.

now i'm trying to debug this error by using Gdb but it is not easy to fix it by myself.
is there any solution or a patch regard to this problem ?
if we get additional information regarding this issue, it would be very helpful for us to investigate this matter .
Thanks.
