I am trying to use -fsanitize=address feature in clang compiler, but I am interested in to see my local project errors only, so I will ignore the incoming error from 3rdparty libraries, specifically I have a project configured to ignore the errors who become from dbus.
My system: cmake version 3.9.5
Linux hostname 4.14.0-2-amd64 #1 SMP Debian 4.14.7-1 (2017-12-22) x86_64 GNU/Linux
clang version 4.0.1-8 (tags/RELEASE_401/final) Target: x86_64-pc-linux-gnu Thread model: posix InstalledDir: /usr/bin

My problem, from the project root dir execute:
mkdir build
cd build
ctest -DCTEST_BINARY_DIRECTORY="." --verbose -S ../CTestCustom.cmake
./src/main
And then the output is:

As you can see I have a "Indirect leak of" from dbus lib.
Solution:
set(CTEST_MEMORYCHECK_TYPE "AddressSanitizer") to
set(CTEST_MEMORYCHECK_TYPE "LeakSanitizer"). interceptor_via_lib:dbus-1 to leak:libdbus-1.This will to send LSAN_OPTIONS instead of ASAN_OPTIONS to the process execution.
