Reconsider Persistent Mode in the Compiler Runtime about aflplusplus, Overflow in <__libqasan_posix_memalign> when len approximately equal to or less than align. To have this option might be a good thing, but this should not be the default behavior as this would slow down the fuzzing significantly. 0:00 Introduction1:28 What is persistent mode3:10 Modifying Damn Vulnerable C Program to use persistent mode5:30 Compiling Damn Vulnerable C Program using af. maybe it is possible but I would prefer that you first check if what you want is actually possible without killing compatability - otherwise the discussion is a waste of time :).
