Segmentation fault with

Dear all,

I am working with the Linux BSP Rev. L4.1.15_1.1.0-ga, on an iMX6 Quadplus based board, and with imx-parser package 4.1.4.

While playing the attached m4a file "B.m4a" with the following command :

gst-launch-1.0 -v  filesrc location=B.m4a   ! decodebin ! audioconvert ! volume ! fakesink

I got a segmentation fault error in "":

(gdb) run
Starting program: /usr/bin/gst-launch-1.0 -v filesrc location=B.m4a \! decodebin \! audioconvert \! volume \! fakesink

Program received signal SIGSEGV, Segmentation fault.

The file B.m4A attached is intentionally not coherent for robustness testing purpose.

I have tried newer versions of imx-parser (4.1.5, 4.1.6 and 4.2.0) but this issue is still present.

Is there any way to prevent this SIGSEGV and make the parser exits with stream error?

Thanks for your help,

I uploded the lib file, could you test it?
