Package: intel-media-va-driver
Version: 20.3.0+dfsg1-1
Severity: important
Tags: ftbfs

Dear Maintainer,

Since my latest debian update, VLC is crashing when playing video with the message:
  Illegal instruction

After a bit of debug in GDB, I have confirmed that the crash comes from:
  /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so

(gdb) bt
#0  0x00007fffa133ba6b in ?? () from /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
#1  0x00007fffa133bb8f in ?? () from /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
#2  0x00007fffa133b2c8 in ?? () from /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
#3  0x00007fffa133bc67 in ?? () from /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
#4  0x00007fffa1342a05 in ?? () from /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
#5  0x00007fffa12c6597 in ?? () from /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
#6  0x00007fffac244e86 in ?? () from /usr/lib/x86_64-linux-gnu/libva.so.2
#7  0x00007fffac245feb in vaInitialize () from /usr/lib/x86_64-linux-gnu/libva.so.2

I am suspecting it is because the package is compiled from a very recent architecture
(i7 with sse4.1 explicitely enabled) which my processor does not support.

I have tryed compiling the package from source, but after tweaking the flags to
set -march=native, the compilation fails:

I am wondering what would be a good solution to at least avoid crashes...
