CMake Options

-DBUILD_fckit=OFF -DENABLE_FORTRAN=OFF \
-DCMAKE_CXX_FLAGS='-fsanitize=address -fno-omit-frame-pointer' \
-DCMAKE_C_FLAGS='-fsanitize=address -fno-omit-frame-pointer' \
-DCMAKE_EXE_LINKER_FLAGS=-fsanitize=address

Create a suppressions file (for example as in atlas/tools/lsan.supp):

leak:libomp
leak:libopen-pal
leak:MPI_Init

Environment variable:

export LSAN_OPTIONS=suppressions=<path-to-lsan.supp>:fast_unwind_on_malloc=0

In LSAN_OPTIONS, the option fast_unwind_on_malloc=0 is required to get a full stack trace in order to suppress MPI_Init.

CMake Options

-DCMAKE_CXX_FLAGS='-fsanitize=undefined -fno-omit-frame-pointer -fno-sanitize-recover=all -fsanitize-blacklist=<path-to-ubsan.blacklist>'

The ubsan.blacklist file contains routines or files where no errors should be reported, for example:

src:*/CGAL/Compact_container.h

The third-party library CGAL (version 4.9) contains a possible error that is typically suppressed this way.
