I've attached the script that I had trouble with. It tries to replicate
one directory structure in another directory, while replacing filenames
and file contents with random data. When compiled with -O1 or -O2
resulting file and directory names are composed only of a's and b's,
but file contents seem properly randomized.
ghc-7.6.2, vector-0.10.0.1, primitive-0.5.0.1, mwc-random-0.12.0.1,
Gentoo Linux i686 3.8.2-pf.

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.
It looks like MWC generates only 0 and 1 for some reason. I've tried to write simple test but everything works fine. Could you post test case and compiler/libraries/OS versions you use?
