Use suppression files or `--ignore-chrome` + +```bash +ASAN_OPTIONS="suppressions=asan.supp" ./test +``` + +### Issue: Performance Too Slow + +**Solution:** Use `-O1` instead of `-O0`, or target specific checks + +```bash +# Only address and leak checking +clang -fsanitize=address,leak -O1 -o test test.c + +# Skip slowest checks +clang -fsanitize=address -O1 -fsanitize-address-space-init-order=false -o test test.c +``` + +### Issue: Cannot Find Source of Leak + +**Solution:** Enable detailed leak information + +```bash +valgrind --leak-check=full \ + --show-leak-kinds=all \ + --track-origins=yes \ + --verbose \ + ./test +``` + +### Issue: MSAN Reports Many Uninitialized Errors + +**Solution:** This often means the code is using uninitialized values.
