Problem running Honggfuzz on simple fauxware.c program

[Theodore Riera]

Hello, I'm trying to run honggfuzz with the following on the simple fauxware.c program in linked in the attachments.

I tried this using different compilers: clang-5.0 and the honggfuzz clang compiler with the following flags: 

    clang-5.0 -fsanitize=address  -fsanitize-coverage=bb fauxware.c -o fauxwareinstru

I ran honggfuzz with the following commands:

../honggfuzz/honggfuzz --input input --workspace output --sancov --sanitizers --stdin_input -- binary/fauxwareinstru

However honggfuzz stops after the first itteration with the following output:

------------------------------[ honggfuzz v1.2 ]-------------------------------

Ok, that's interesting, saved 'output/honggfuzz.input.0.fauxwareinstru.fuzz' as 'output/SIGABRT.PC.7ffff6efa428.STACK.149b703183.CODE.-6.ADDR.(nil).INSTR.cmp____$0xfffffffffffff000,%rax.fuzz'

It seems that 'output/SIGABRT.PC.7ffff6efa428.STACK.149b703183.CODE.-6.ADDR.(nil).INSTR.cmp____$0xfffffffffffff000,%rax.fuzz' already exists, skipping

I also have a log file that I left in attached files. This might be related to clang and be a very newbie question sorry in advance if that's the case. I was hoping for some advice and a way to move forward with this .

Thanks in advance!
