Hmm, just a random shot (shouldn't be the case, but just to be on the safe
side) -- could you please try

echo 0 > /proc/sys/kernel/randomize_va_space

to see whether it removes the segfault by any chance?

I don't know how exactly execution of real-mode code through libx86 works,
but this might be worth trying before starting the next round of
bisection.
