Good idea. The testcases should be adapted to the code paths in the GCC
generators though: for instance, binomial with p > .5 isn't covered there.
And BINS should be increased: for instance in the binomial(.3, 5500)
testcase the most frequent outcomes are around 1650, but BINS only covers
outcomes up to 100.
