... there's a problem that g++ 8.2.0 doesn't like the compiler flags emitted by llvm-config-7:
<cut> g++ `llvm-config-7 --cxxflags` -fno-rtti -fpic -Wall -D_FORTIFY_SOURCE=2 -g -Wno-pointer-sign -DVERSION=\"2.52b\" -Wno-variadic-macros -shared afl-llvm-pass.so.cc -o ../afl-llvm-pass.so `llvm-config-7 --ldflags` -Wl,-z,relro -Wl,-z,now g++: error: unrecognized command line option '-Wcovered-switch-default'; did you mean '-Wno-switch-default'? g++: error: unrecognized command line option '-Wstring-conversion'; did you mean '-Wint-conversion'? </cut> Ah, it's: https://bugs.debian.org/914838 llvm-7: llvm-config-7 emits unsupported compiler option DS -- 4096R/DF5182C8 (sten...@debian.org) http://www.danielstender.com/
