Hi Alexander,

I execute as you did, why the fuzz time are different?
Some takes little time, some takes much time.

$ ulimit -v 2097152; time ./ &> fuzz.log

real    0m7.820s
user    0m1.257s
sys     0m1.567s

real    0m5.781s
user    0m0.761s
sys     0m1.560s

real    0m8.124s
user    0m0.998s
sys     0m1.937s

real    0m16.276s
user    0m10.148s
sys     0m2.279s

real    0m6.846s
user    0m1.135s
sys     0m1.727s

real    1m33.440s
user    1m12.453s
sys     0m10.338s

This leads to different results. Some have fuzz-err.log while some did not.
Some fuzz-err.log have serval hashes while some have few.
Why the results are different ?
