Continue_on_error (COE) is a new functionality in the Address Sanitizer runtime which provides a new “checked build” for C and C++. This new runtime mode diagnoses and reports hidden memory safety errors, with zero false positives, as your application runs. It's enabled by simply compiling with -fsanitize=address and setting an environment variable.
