Sebastian a1a695dcda checkio: Add missing id "invalidScanfFormatWidth_smaller" to errorlist output (#1533) 2018-12-20 21:14:02 +01:00
Paul Fultz II 025881cf35 Fix issue 8829: Condition '...' is always true (int buf[42]; if(buf != NULL){})
This makes arrays non-null in valueflow, so it can catch comparisons against null that is always true:

```cpp
void f(void) {
   int buf[42];
   if( buf != 0) {;} // << always true
}
```

rebnridgway 42a65c5160 Fix crash bug #8579 (#1238)
* Added declaration for deletePrevious function

* Added definition for deletePrevious function

* Fixed crash from deleteThis invalidating pointers

The crash was caused by deleteThis() invalidating the pointer to a constant variable usage.  This happened when a usage followed an assignment.  This fixes bug #8579.

* Added tokensFront to match tokensBack

This means deletePrevious can set the list's front if necessary.

* Initialised tokensFront in appropriate places

* Switched to using default Token constructor

* Switched to using Token default constructor

* Switched to using default constructor for Token

* Added missing argument to Token constructor

* Changed to use default constructor for Tokens

* Switched to using default constructor for Tokens

* Switched to using default constructor for Token

* Added new test for deleting front Token

Also made sure to use the correct constructor for Token in other tests.

* Syntax error

* Replaced tokensFront and tokensBack with a struct

This decreases the size of the Token class for performance purposes.

* Replaced tokensFront and tokensBack with a struct

* Added tokensFrontBack to destructor

* Reworked to use TokensBackFront struct

Also ran astyle.

* Reworked to use TokenList's TokensFrontBack member

* Reworked to use TokensFrontBack struct

* Reworked to use TokensFrontBack struct

* Reworked to work with TokensFrontBack struct

* Removed unnecessary scope operator

* Added missing parentheses

* Fixed syntax error

* Removed unnecessary constructor

* Default constructor now 0-initialises everything

This is safer for not using a temporary TokensFrontBack object, and doesn't use delegating constructors which aren't supported yet.

* Fixed unsafe null check

* Added missing explicit keyword

* Fixing stylistic nits

Removed default constructor as it has been superseded by the single-argument constructor with a default argument value.
Renamed listEnds to tokensFrontBack.
Fixed if statement that was supposed to be adding safety but would actually cause a crash if tokensFrontBack was null.

* Fixing stylistic nits

Removed default constructor and replaced it with a single-argument constructor with a default value.

* Fixing stylistic nits

Renamed _listEnds to _tokensFrontBack.

* Fixing stylistic nits

Renamed _listEnds to _tokensFrontBack.
