Using Libfuzzer on a library - linking the library to the fuzz target
...build object files/shared libraries with -fsanitize=fuzzer, and the libFuzzer main won't be linked, if this makes your build process easier). - with just the *fuzzer *flag, it looks for the LLVMFuzzerTestOneInput. 3. I've run a quick grep and can't find anything that would match "apifunc() resp=0x7ff38f83ac20 uninitialized, fixing it." in libFuzzer (or compiler-rt). What version of compiler-rt/llvm/clang are you trying this with? - This was an oversight on my part, it was a log dump from the library and somehow I mistook it be from libfuzzer. (I am using Clang 9 btw). 4. Have...

The libfuzzer log has a line which says - *apifunc() resp=0x7ff38f83ac20 uninitialized, fixing it*. I am not sure what this means. Also, I can see that the apifunc is called and it runs but it does not show up in the *NEW_FUNC[x/xxx]: *log lines in the libfuzzer output. To enable fuzzing. Fir...
