GCC-Sanitizer
Determine how to correctly work with these sanitizers
Extract of the old documentation:
Memory Errors
-------------
Check if the submitted code compiles without warnings and enable AddressSanitizer, a fast memory error detector:
.. code-block:: make
CC=gcc
CFLAGS=-Wall -Werror -Wextra -Wpedantic -std=c11 -fsanitize=address
ex: ex.c
Memory Leaks
------------
Check if the submitted code compiles without warnings and enable LeakSanitizer, a memory leak detector:
.. code-block:: make
CC=gcc
CFLAGS=-Wall -Werror -Wextra -Wpedantic -std=c11 -fsanitize=leak
ex: ex.c
Undefined Behavior
------------------
Check if the submitted code compiles without warnings and enable UndefinedBehaviorSanitizer, a fast undefined behavior detector:
.. code-block:: make
CC=gcc
CFLAGS=-Wall -Werror -Wextra -Wpedantic -std=c11 -fsanitize=undefined
ex: ex.c
.. note::
