some projects have no improvement in coverage

happens for redux, sharp bytes, tslib, jimp, jpeg-js

at least for redux this does seem to be because some inputs hit the same edges more times, i.e. not a bug in the fuzzer itself.

idk about that, but the problem with redux is basically difficult condition to pass through and functions that aren't used by the library

[mayant15]

oh yes, sorry I meant why new inputs are added to the corpus despite no improvement in coverage.
