The -msan option compiles Go code to use the memory sanitizer. This is intended for use when linking with C/C++ code compiled with -fsanitize=memory. When memory blocks are passed back and forth between C/C++ and Go, code in both languages will agree as to whether the memory is correctly initialized or not, and will report errors for any use of uninitialized memory.
