            Bug ID: 44289
           Summary: Investigate `nan` returning random distributions in
                    fuzzing tests.
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: eric at efcs.ca

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`.
