clang is working fine on debian (my Raspery pi 3) (no need to add -Wno-array-bounds to the src/Makefile) and also working fine on Fedora 25 to compile gnu-apl, and it run fine after compile.
on debian I did: apt-get install clang on fedora25 I did: dnf install clang all I had to do after that was: ./configure CC=clang CXX=clang++ (add your own configure options here like --with-sqlite ...) It compile a little bit faster (especially on Raspberry pi 3) near two time faster (9 minutes vs 5 minutes) It run at the same speed as far I know. my ever 2 cents, Xtian.
