A code sanitizer is a programming tool that detects bugs in the form of undefined or suspicious behavior by a compiler inserting instrumentation code at runtime. The class of tools was first introduced by Google's AddressSanitizer (or ASan) of 2012, which uses directly mapped shadow memory to detect memory corruption such as buffer overflows or accesses to a dangling pointer (use-after-free).
For example, 80005 is success even though it starts with 8. If padded to 8 digits this becomes clear: 00080005. This is somewhat contrived since generally success is 0 which is clearly a success code. Programmatic ways to check for failure status are to test for negative or to use a system-defined macro. [5]
It also identifies syntax errors. It is rules based, and uses a number of heuristics to identify bad code. [1] Cpplint is not perfect, as it can suffer from occasional false positives and negatives. Nevertheless, it is still a very useful tool for style enforcement. [2] Moreover rules can be fine-grained selected using the options --verbose and ...
Pick one of the errors from the table below. Work through the pages in the Latest Database Dump List, fixing any errors you find. Edit the list and remove any articles you have fixed. Update the date you checked in the other columns as (MM), (DD), (YYYY). If you finished the whole list, mark it Done (Optional) - Return to step 1 and try another ...
It is the responsibility of the programmer to write code that never invokes undefined behavior, although compiler implementations are allowed to issue diagnostics when this happens. Compilers nowadays have flags that enable such diagnostics, for example, -fsanitize=undefined enables the "undefined behavior sanitizer" in gcc 4.9 [3] and in clang ...

Dereferencing any of these variables could cause a segmentation fault: dereferencing the null pointer generally will cause a segfault, while reading from the wild pointer may instead result in random data but no segfault, and reading from the dangling pointer may result in valid data for a while, and then random data as it is overwritten.
Many protocols use an XOR-based longitudinal redundancy check byte (often called block check character or BCC), including the serial line interface protocol (SLIP, not to be confused with the later and well-known Serial Line Internet Protocol), [8] the IEC 62056-21 standard for electrical-meter reading, smart cards as defined in ISO/IEC 7816, and the ACCESS.bus protocol.
