Same here, I used mwc-random to generate random strings. It works in
ghci and when compiled with -O0, but with -O1 and -O2 I've been getting
exclusively a's and b's.

I am using GHC 7.6.1 mwc-random 0.12.0.1 vector 0.9.1 primitive 0.4.1

Nope that isn't the case either. Even if I make use of defaultSeed through create the problem still remains. The problem seems to be in the generation of a vector of (a,a) i.e in the part
V.generateM ((round $ p*(fromIntegral $ l*z)) `div` 2) (\i-> R.uniformR ((0,0) , (l-1,l-1)) gen)
in line 16. Thanks again.
I've tried to run you program and I've got approximately same results regardless of optimization level. Which versions of GHC, mwc-random, vector and primitive do you use?
