I don't have Shredder 8, but M.Meiler's WM Test results (A1400/256 MB Hash) of
Shredder 8 (UCI) indicate that 76,94,98 cannot be solved at ply 1 nor within 15
seconds:

(#/ply depth/sec.)

76) 23 / 1200 (not solved in 20 min.)
94) 20 /  413
98) 20 /  215

I assume cb-native Shredder 8 with 128 MB isn't so much different... OTOH, you
can always crosscheck that on your system by

1. delete the learning file (AFAIK shredder8.plr),
or move into to another directory temporarily if you want to keep it

2. run the test position in normal analysis mode, 1 pv

(I usually don't use automatic testsuite processing.)
