Questions tagged [leak-sanitizer]

LeakSanitizer (LSan) is a memory leak detector for GCC and Clang.

LeakSanitizer (LSan) is a run-time memory leak detector, available since Clang 3.4 and GCC 4.9. It is automatically enabled with AddressSanitizer (ASAN), but can also operate independently.

Once enabled at compile time using the -fsanitize=address or -fsanitize=leak, it will automatically be enabled at runtime. To disable that, use LSAN_OPTIONS=detect_leaks=0.
