afonso360 opened PR #4895 from continue-on-trap to main:

:wave: Hey,

This PR changes how we deal with traps in fuzzgen. Instead of discarding the entire function outright we continue onto the next function input and test those as well. Maybe they won't trap!

I haven't done any benchmarking on this, but it also didn't seem to decrease execs/s in any meaningful way when I tested it locally.

Thanks @jameysharp for the suggestion!
