Guideline

alloca_bounds ARR32-C. Ensure size arguments for variable length arrays are in a valid range
Body of function falls-through MSC37-C. Ensure that control never reaches the end of a non-void function
comparable_char_blocks EXP42-C. Do not compare padding data
dangling_pointer DCL30-C. Declare objects with appropriate storage durations
dangling_pointer MEM30-C. Do not access freed memory
differing_blocks ARR36-C. Do not subtract or compare two pointers that do not refer to the same array
division_by_zero INT33-C. Ensure that division and remainder operations do not result in divide-by-zero errors
Exhaustively verified. FLP37-C. Do not use object representations to compare floating-point values
float_to_int FLP34-C. Ensure that floating-point conversions are within range of the new type
incompatible declaration DCL40-C. Do not create incompatible declarations of the same function or object
index_bound DCL38-C. Use the correct syntax when declaring a flexible array member
index_in_address ARR30-C. Do not form or use out-of-bounds pointers or array subscripts
index_in_address ARR39-C. Do not add or subtract a scaled integer to a pointer
initialisation DCL41-C. Do not declare variables inside a switch statement before the first case label
initialisation EXP33-C. Do not read uninitialized memory
malloc MEM31-C. Free dynamically allocated memory when no longer needed
match format and arguments STR32-C. Do not pass a non-null-terminated character sequence to a library function that expects a string
match format and arguments FIO47-C. Use valid format strings
mem_access EXP34-C. Do not dereference null pointers
mem_access EXP40-C. Do not modify constant objects
mem_access STR30-C. Do not attempt to modify string literals
mem_access STR31-C. Guarantee that storage for strings has sufficient space for character data and the null terminator
mem_access MEM35-C. Allocate sufficient memory for an object
non-static declaration follows static declaration DCL36-C. Do not declare an identifier with conflicting linkage classifications
non-terminating FLP30-C. Do not use floating-point variables as loop counters
out of bounds read ARR38-C. Guarantee that library functions do not form invalid pointers
out of bounds read STR34-C. Cast characters to unsigned char before converting to larger integer sizes
out-of-range argument FLP32-C. Prevent or detect domain and range errors in math functions
pointer arithmetic STR38-C. Do not confuse narrow and wide character strings and functions
pointer arithmetic ERR33-C. Detect and handle standard library errors
separated EXP30-C. Do not depend on the order of evaluation for side effects
shift INT34-C. Do not shift an expression by a negative number of bits or by greater than or equal to the number of bits that exist in the operand
signed_downcast INT31-C. Ensure that integer conversions do not result in lost or misinterpreted data
signed_overflow INT32-C. Ensure that operations on signed integers do not result in overflow
type specifier missing DCL31-C. Declare identifiers before using them
unclassified ("free expects a free-able address") MEM34-C. Only free memory allocated dynamically
unclassified ("function type matches") EXP37-C. Call functions with the correct number and type of arguments
unclassified (variadic) EXP47-C. Do not call va_arg with an argument of the incorrect type
unsigned overflow INT30-C. Ensure that unsigned integer operations do not wrap
valid_char STR37-C. Arguments to character-handling functions must be representable as an unsigned char
variadic MSC39-C. Do not call va_arg() on a va_list that has an indeterminate value
