So did AFL generate a test case for this one?  I'm not sure where it could ever be used uninitialized, given that wtap_file_read_number() should, if it returns a value that's neither -1 nor 0, fill in the variable to which it's handed a pointer; perhaps afl-gcc's data flow analysis missed something, or perhaps I did.
