Dear Maintainer,
I tried to reconstruct the given backtrace in [1].
So the actual issue seems to be a "movq" instruction which
seems to be due to [3] a SSE2 instruction, which might
the "Pentium III M" is lacking, like Stefan already noted.
I am not sure where the current Debian baseline could be
consulted regarding this, maybe [4] could give a hint.
Kind regards,
Bernhard
