+MemorySanitizer is a detector of uninitialized memory use. It consists of a
compiler instrumentation module and a run-time library.
Typical slowdown introduced by MemorySanitizer is **3x**.
+Here is a not comprehensive list cases when MemorySanitizer will report an error:
+
+* Conditional branches controlled by uninitialized values.
+* Using uninitalized pointers for memory accesses.
+* Passing and returning uninitialized values to/from function calls. Can be disabled with ``-fno-sanitize-memory-param-retval``.
+* Passing uninitialized data into libc calls.
