            Bug ID: 31950
           Summary: libfuzzer: Fixed word size
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: kurt at roeckx.be
                CC: kcc at google.com, llvm-bugs at lists.llvm.org

There is currently this in FuzzerDictionary.h:
typedef FixedWord<27> Word; // 28 bytes.

When checking a SHA256 or similar with memcpy(), it's not big enough. Can you
make that 64 bytes instead?
