Hello Karsten,
I tried to collect some more information for the maintainer and
could reproduce this (or nearly) the same SIGILL with a qemu VM limited
to a pentium class CPU.
The instruction in question might these below:
0xb78816bb <+75>: movd 0x4(%esi),%xmm2 (here I received the SIGILL)
0xb78816fb <+139>: pminud %xmm2,%xmm3 (thats from your backtrace
the similar address offset 0x...6fb)
Both access a register xmm2/xmm3 which seems to be "just"
available on CPUs having the SSE extension.
Therefore it would be interesting to know with which CPU you
are getting this SIGILL (e.g. 'lscpu' or 'cat /proc/cpuinfo').
Otherwise finch seems not to depend directly from intel-media-va-driver,
and from the package description if your CPU is older than "Broadwell",
then you might even not benefit from this package. Therefore a
workaround might be to uninstall intel-media-va-driver if no
other dependencies require it?
Kind regards,
Bernhard

The program being debugged was signaled while in a function called from GDB.
GDB remains in the frame where the signal was received.
To change this behavior use "set unwindonsignal on".
Evaluation of the expression containing the function
(__dlopen) will be abandoned.
When the function is done executing, GDB will silently stop.
