[PATCH 2/3] tests: Fix uninitialized byte in test_visitor_in_fuzz

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



One byte in the local buffer stays uninitialized, at least with the
first iteration, because of the double decrement in the
test_visitor_in_fuzz(). This is what Valgrind does not like and not
critical for the test itself. So, reduce the number of the memory
issues reports.
