Running asan/lsan tests requires changing the build and setting a few environment variables.
Changes to args.gn (ie, out/Release/args.gn):
is_asan = true is_lsan = true
Setting up environment variables and running the test:
$ export ASAN_OPTIONS="symbolize=1 external_symbolizer_path=./third_party/llvm-build/Release+Asserts/bin/llvm-symbolizer detect_leaks=1 detect_odr_violation=0" $ export LSAN_OPTIONS="" $ out/Release/browser_tests
Stack traces (such as those emitted by base::debug::StackTrace().Print()) may not be fully symbolized. The following snippet can symbolize them:
$ out/Release/browser_tests 2>&1 | ./tools/valgrind/asan/asan_symbolize.py
