<pre>Some of the random distributions return NaN when being fuzzed. The likely cause
is that the fuzzer is feeding in data that violates the pre-conditions, but we
should figure out if libc++ can handle these precondition violations better.
See `random_distribution_helper` in `libcxx/fuzzing/fuzzing.cpp`.</pre>
