Four months ago, I reported a bug in gaussian-random when either optional parameter min or max is nil but not both are nil. The docstring has been modified since then but the code is still the same and the bug remains. In such a situation it is possible to enter an infinite loop.
pushed (with some whitespace changes), and committed a test also that demonstrates the failure.

thanks, and sorry for the delay!
