<pre>
    When building using CMake with ASAN and AFL++ compilers (afl-cc/afl-c++), I am getting `clang frontend command failed with exit code 139 error`. If I remove the `-DSANITIZER=address` switch, it builds just fine.

If I build using the non AFL compilers (just pass `clang-14` and `clang++-14` instead of `afl-cc` and `afl-c++`), then ASAN build works fine too. 

Does anyone know why or what this error is about?
