Sanitizer

Address Sanitizer

Address Sanitizer (ASan) is a fast memory error detector that detects use-after-free and out-of-bound bugs in C/C++ programs. It uses a compile-time instrumentation to check all reads and writes during the execution. In addition, the runtime part replaces the malloc and free functions to check dynamically allocated memory.

Thread Sanitizer

Thread Sanitizer (TSan) is a fast data race detector for C/C++ programs. It uses a compile-time instrumentation to check all non-race-free memory access at runtime. Unlike other tools, it understands compiler-builtin atomics and synchronization and therefore provides very accurate results with no false positives (except if unsupported synchronization primitives like inline assembly or memory fences are used).

ASan Nightly Project

The ASan Nightly Project involves building a Firefox Nightly browser with the popular AddressSanitizer tool and enhancing it with remote crash reporting capabilities for any errors detected.
