AFLplusplus: afl-cov error on AFL++ output directory

Hi . Sorry to open-up the issue here, it was not possible to open the issue at the afl-cov github (vanhauser-thc version) I am using https://github.com/vanhauser-thc/afl-cov to measure the line coverage on an app that is fuzzed with afl++ .

I’m basically using the afl-cov.sh to facilitate the process, using afl-cov.sh or afl-cov will actually results in a error .

I’m using the command :

~/afl-cov/afl-cov.sh /home/samstack/fuzzing-targets/tiff-4.0.4-cov/output1/default "/home/samstack/fuzzing-targets/tiff-4.0.4-cov/tools/tiffinfo @@"

and error :

Traceback (most recent call last):
  File "/home/samstack/afl-cov/afl-cov", line 1227, in <module>
    sys.exit(main())
  File "/home/samstack/afl-cov/afl-cov", line 80, in main
    if not validate_cargs(cargs):

  File "/home/samstack/afl-cov/afl-cov", line 727, in run_cmd
    with open(fh.name, 'r', 'rb') as f:
TypeError: an integer is required (got type str)

Help wanted!

It seems that is a problem with python scripts.

I am looking for a solution to this.

tnx
