--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Julian Taylor from comment #0) > when linking a file with -fsanitize=* the sanatizer library (e.g. -ltsan is > placed before the object on the command line: > > gcc-4.10 test.c -fsanitize=thread -v -fPIC -shared 2>&1 | grep --color tsan > > [...] -ltsan /tmp/cc6ovqw5.o -lgcc --as-needed -lgcc_s [...] This might be specific to libtsan, not all the sanitizer libs, I think tsan is handled differently. On a sort of not really related point, the gcc driver links -lstdc++ before -llsan which means C++ programs linked to libstdc++ don't get the replacement operator new from lsan, it should be -llsan -lstdc++
