I was testing my new fuzzing tool and I fuzzed cflow 1.5. During the fuzzing run, I found that cflow get stuck at a particular point. Following is the output message:
$cflow $POC
....
..../home/sanjay/tools/cflow-1.5/src/cflow: /tmp/cflow-ex-421-05-03-18:0940.c:325: this is the place of previous definition
the input that caused this behavior is attached with the mail.
