If you fuzzing does not run, afl-fuzz might need more memory, set\nAFL_MEM to a high value, e.g. 700 for 700MB\n\n\n## When to use it\nwhen normal afl-dyninst is crashing the binary and qemu mode -Q is not\nan option.\nDynamorio is x10-50 slower than Qemu, 25x slower than dyninst - however 10x\nfaster than Pintool, and works additionally on ARM and AARCH64.\nIn memory fuzzing (function fuzzing) is a much faster option and implemented\nin a future release.\n\n\n## Who and where\nhttps://github.com/vanhauser-thc/afl-dynamorio\n\nMarc \"van Hauser\" Heuse \u003cmh@mh-sec.de\u003e || \u003cvh@thc.org\u003e\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvanhauser-thc%2Fafl-dynamorio","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fvanhauser-thc%2Fafl-dynamorio","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvanhauser-thc%2Fafl-dynamorio/lists"}
