This option instructs the compiler to check that the size of a variable length array is positive. -fsanitize=null This option enables pointer checking. Particularly, the application built with this option turned on will issue an error message when it tries to dereference a NULL pointer, or if...

-fno-access-control Turn off all access checking. This switch is mainly useful for working around bugs in the access control code. -fcheck-new Check that the pointer returned by "operator new" is non-null before attempting to modify the storage allocated. This check is normally unnecessary ...
This standard is substantially completely supported, modulo bugs, floating-point issues (mainly but not entirely relating to optional C11 features from Annexes F and G) and the optional Annexes K (Bounds-checking interfaces) and L (Analyzability). The name c1x is deprecated. gnu90 gnu89 GNU ...
UndefinedBehaviorSanitizer gained a new sanitization option,-fsanitize=bounds-strict, which enables strict checking of array bounds. In particular, it enables-fsanitize=boundsas well as instrumentation of flexible array member-like arrays. Type-based alias analysis now disambiguates accesses to different...
As you know, the C++ language assumes that the programmer is always correct. Therefore C++ compilers don't add additional checks to the program, such as checks for null pointer dereference or out-of-bounds array access. This is good, because C++ programs run as fast as possible, and this ...
