Hi cfe-users - I'm using clang-3.4 from Ubuntu Trusty and trying to get leak sanitizer integrated with a project. The project builds with -fsanitize=address passed to all compile and link lines, and reports various memory errors, so I know it is working. When run with ASAN_OPTIONS="detect_leaks=1" in the environment leaks are reported at exit, so that is working as well.
I have a suppressions file that works correctly when LSAN_OPTIONS="suppressions=etc/asan.suppressions" is set in the shell environment. The expected suppressions are applied and the suppressed leaks are not reported at exit. The file looks like this: $ cat ./etc/asan.suppressions # ignore v8 for now leak:v8:: However, if I try to set this file as the suppressions file with --fsanitize-blacklist=etc/asan.suppressions, then the suppressions are not applied, and all of the leaks I would expect to have been suppressed are still reported. I know that clang actually is consuming the file, because if I put a malformed line into the suppressions file the build fails with: clang: error: malformed sanitizer blacklist: 'Malformed line 1: 'aslaskdfj'' I'm passing both -fsanitize=address and -fsanitize-blacklist=etc/asan.suppressions to both the compile and link stages of the build. Obviously, I can just use LSAN_OPTIONS, but the blacklist would I think be preferable if I could get it to work. What am I doing wrong? Also, a question about the blacklist that does not seem to be answered in the docs: Does the blacklist file get read on each execution of the binary built with -fsanitize-blacklist, and therefore needs to be kept with the binary? Or are the contents of the blacklist file read at compile time and baked into the executable so that the binary can be used standalone? I'm hoping the latter, as what I would really like to use is __lsan_default_suppressions, but it appears that that is not available until clang-3.5 (it is mentioned in sanitizer/lsan_interface.h for clang-3.5, but not for clang-3.4), and unfortunately I need this integration to work with clang-3.4.
