Sanitizers: Detect memory errors and data races
***********************************************
By default, sanitizers are bundled in GCC and Clang/LLVM. One can enable
sanitizers with GCC >= 4.8 or LLVM >= 3.1, But some distributions might package
sanitizers separately. Here is a list of supported sanitizers with
