Damn, you guys found a bug in my venix emulation:

% echo 99k2vp8opq | ./git/venix/tools/vm86venix/venix= ./git/venix/tools/vm86venix/disbt/usr/bin/dc
pid 70803 (veni= x): sigreturn eflags =3D 0x0

I'll have to = see how hard it is to setup my Rainbow 100B running Venix and if the benchm= ark works there or not.
Or if this is a bug in venix's dc...<= /div>

altho i date back to those days, i do= n=E2=80=99t recall using that benchmark.
when i=E2=80=99ve needed something bc-ish to take some time, i normally
use a bessel function from bc -l
