hello, when I ran AFL fuzz a demo program, the stoch-fuzz didn't respond. It keep stopping at “phantom file is create, please execute afldemo.phantom to communicate with the daemon”

I tried to install StochFuzz with build.sh, and the clang version in my environment is 10.0.0, but this script failed with message: "clang-6.0 or a newer version is required".
So I checked this script and find that the regular expression that you used when matching with clang version output, is not correct if the version number is bigger than 9:
clang --version | head -n 1 | grep -o -E "[[:digit:]].[[:digit:]].[[:digit:]]" | uniq | sort
Maybe this is better：
clang --version | head -n 1 | grep -o -E "[0-9]{1,2}.[0-9].[0-9]" | uniq | sort

ERROR call handler for PIE programs is unimplemented :./rewriter_handlers/handler_call.c:101
so your tool does not support PIE programs ?

While trying to build dependencies using the build.sh, it turns out the glib build fails.
Using the latest commit on master and the OS is Ubuntu 18 LTS.

OS: ubuntu 22
reproduce:

./build.sh
sudo apt install libunwind-dev libglib-dev
replace all libasan.so.4 with libasan.so.6 in src/Makefile
cd src && make release
