This may or may not be analogous. How hard is it to build a base/ports program with clang from ports? If it's a simple matter of make CC=/usr/local/bin/cc CFLAGS=-fsanitize=undefined then it makes little difference whether the base compiler includes the libraries for UBSan reporting. jca@ WDYT, should I first target devel/llvm to have UBSan working or go straight to /usr/src? Thanks Greg
