Clang supports -fsanitize=leak which simply links a standalone lsan library (no instrumentation at compile time required). Perhaps gcc can add such option too. But: we do not test -fsanitize=leak on anything other than tiny tests, so we truly support only the lsan+asan use case. We'll need to update the wiki page to have this all explained in detail, thanks for raising these questions.
