The following comes to mind, although it feels _quite_ nasty: export LD_PRELOAD=libasan.so export CC="gcc -fsanitiser..." export CXX=... configure && make && make install I understand that most people will not like it, so I won't mention it again ;-) Couple of suggestions: - as mentioned by Eric - we want to detect and error out if user requests a sanitizer that is not available. - a big warning is due, since running make check _will_ fail, if the library is not preloaded.
