Error Codes

This page provides an overview of each error code. You can suppress errors using the Suppressions Control Panel (see Customizing Options on Windows). The following sections provide a detailed description of each error including:

A brief explanation of what problem has been detected.
An example program that generates a similar error.
Output that would be generated by running the example, with annotations indicating what the various pieces of the diagnostic mean and how they should be interpreted in identifying your own problems. The exact appearance of the error message may depend on how Insure++ is currently configured.
A brief description of ways in which the problem might be eliminated.

Sometimes you will see values identified as <argument #> or <return> instead of names from your program. In this case, <argument n> refers to the nth argument passed to the current function (i.e., the argument where the error was detected), and <return> refers to a value returned from the function indicated.

Code	Description	Reported	Platform
ALLOC_CONFLICT	Mixing malloc/free with new/ delete	Runtime	Windows/Unix
(badfree)	Memory was allocated with `new` or `new[]` and an attempt was made to free it with `free`.	Runtime	Windows/Unix
(baddelet)	Memory was allocated with `malloc` and an attempt was made to free it with `delete` or `delete[]`.	Runtime	Windows/Unix
(badhandle)	Memory is allocated by one heap and freed by a different heap	Runtime	Windows

Code	Description	Reported	Platform
BAD_DECL	Incompatible global declarations	Compilation Runtime	Windows/Unix
(sign)	Types differ only by sign, e.g., `int` vs. `unsigned int`	Compilation	Windows/Unix
(compatible)	Fundamental types are different but they happen to have the same representation on the particular hardware in use, e.g., `int` vs. `long` on machines where both are 32-bits, or `int *` vs. `long` where both are 32-bits.	Compilation	Windows/Unix
(incompatible)	Fundamental types are different, e.g., `int` vs. `double`	Runtime	Windows/Unix
(other)	A problem other than an argument type mismatch is detected, such as passing the wrong number of arguments. Error messages are classified according to this scheme and can be selectively enabled or disabled	Compilation	Windows/Unix

Code	Description	Reported	Platform
BAD_PARM	Mismatch in argument type.	Compilation	Windows/Unix
(sign)	Types differ only by sign, e.g., `int` vs. `unsigned int`	Compilation	Windows/Unix
(compatible)	Fundamental types are different but they happen to have the same representation on the particular hardware in use, e.g., `int` vs. `long` on machines where both are 32-bits.	Compilation	Windows/Unix
(incompatible)	Fundamental types are different, e.g., `int` vs. `double`	Compilation	Windows/Unix
(pointer)	This is not an error class, but a keyword used to suppress messages about mismatched pointer types, such as `int ` vs. `char `.	Compilation	Windows/Unix
(union)	Forces a declared union argument to match only a similar union as an actual argument. If this is suppressed, you may pass any of the individual union elements to the routine, rather than the union type, or pass a union to a routine which expects one of the union-elements as an argument.	Compilation	Windows/Unix
(other)	A problem other than an argument type mismatch is detected, such as passing the wrong number of arguments. Error messages are classified according to this scheme and can be selectively enabled or disabled	Compilation	Windows/Unix

Code	Description	Reported	Platform
DEAD_CODE	Code is not evaluated, has no effect, or is unreachable	Compilation	Windows/Unix
(emptyloopbody)	Loop body is empty.	Compilation	Windows/Unix
(emptystmt)	The statement is empty.	Compilation	Windows/Unix
(noeffect)	Code has no effect.	Compilation	Windows/Unix
(notevaluated)	Code is not evaluated.	Compilation	Windows/Unix

Code	Description	Reported	Platform
DELETE_MISMATCH	Mismatch between `new`/`new[]` and `delete`/`delete[]`	Runtime	Windows/Unix
(bracket)	`new`, `delete[]`	Runtime	Windows/Unix
(nobracket)	`new[]`, `delete`	Runtime	Windows/Unix

Code	Description	Reported	Platform
READ_OVERFLOW		Runtime	Windows/Unix
(normal)	Reading overflow's memory	Runtime	Windows/Unix
(nonull)	String is not `NULL`-terminated within range	Runtime	Windows/Unix
(string)	Alleged string does not begin within legal range	Runtime	Windows/Unix
(struct)	Structure reference out of range	Runtime	Windows/Unix

Code	Description	Reported	Platform
READ_UNINIT_MEM	Reading uninitialized memory	Runtime	Windows/Unix
(copy)	Copy from uninitialized region	Runtime	Windows/Unix
(read)	Use of uninitialized value	Runtime	Windows/Unix

Code	Description	Reported	Platform
RETURN_INCONSISTENT	Function has inconsistent return type	Compilation	Windows/Unix
(level 1)	No declaration, returns nothing	Compilation	Windows/Unix
(level 2)	Declared `int,` returns nothing	Compilation	Windows/Unix
(level 3)	Declared non-`int`, returns nothing	Compilation	Windows/Unix
(level 4)	Returns different types at different statements	Compilation	Windows/Unix

Code	Description	Reported	Platform
UNUSED_VAR	Unused variables	Compilation	Windows/Unix
(assigned)	Variable is assigned but never used	Compilation	Windows/Unix
(unassigned)	Variable is never used	Compilation	Windows/Unix

Code	Description	Reported	Platform
WRITE_OVERFLOW		Runtime	Windows/Unix
(normal)	Writing overflows memory	Runtime	Windows/Unix
(struct)	Structure references out of range	Runtime	Windows/Unix
