This was most likely introduced when the checks were changed to run on

Take care to warn about cases where casts destroy the pointer, such as
uint8_t f() {
void* x = malloc(1);
return (uint8_t)x;

template simplifier: ignore alias template definitions with syntax errors ( #2169 )
...
Is not allowed to define a type in an alias template definition.
This code:
template<int N>
using A1 = struct B1 { static auto constexpr value = N; };
A1<0> a1;
produces this output:
2: } ;
3: struct B1 { static const auto value = 0 a1 ;
test.cpp:2:57: error: Analysis failed. If the code is valid then please
report this failure. [cppcheckError]
using A1 = struct B1 { static auto constexpr value = N; };
^
because it tries to instantiate the invalid alias template definition
and generates garbage code.
2019-09-11 19:31:15 +02:00

Track lifetime across multiple returns
...
This will now warn when doing something like this:
```cpp
template <class T, class K, class V>
const V& get_default(const T& t, const K& k, const V& v) {
auto it = t.find(k);
if (it == t.end()) return v;
return it->second;
}
const int& bar(const std::unordered_map<int, int>& m, int k) {
auto x = 0;
return get_default(m, k, x);
}
```
The lifetime warning is considered inconclusive in this case.
I also updated valueflow to no tinject inconclusive values unless `--inconclusive` flag is passed. This creates some false negatives because library functions are not configured to not modify their input parameters, and there are some checks that do not check if the value is inconclusive or not.

Add two Qt macros that were missing
* Fix issue with __declspec and final
This change is a bit naive but it fixes the issues I was having when combining __declspec(dllexport) and final classes. Without the fix I get errors along the line of "The code 'class x final :' is not handled. You can use -I or --include to add handling of this code. "

leakNoReturnVar: Don't break early ( #2095 )
...
There seems to be no reason for stopping checking the scope if a call to
free() is seen (or fclose() or realloc()), so just continue checking.
Also, if there are multiple arguments, check all, perhaps there are more
memory leaks to warn about.

Fix FP: Unitialized variable when using a pointer

This fixes the FP in cases like this:

bool b;
bool * x = &b;
if (x != nullptr)
x = 1;
}
```
It tracks the indirection of the uninit value in valueflow.

leakNoVarFunctionCall: Use AST more ( fix #9252 ) ( #2086 )
...
Use the AST a little bit more to improve the check. In order to do so,
rewrite the check to work from the outer function first and then check
the arguments, instead of the other way around.
It also fixes Trac ticket #9252 , no warning is now given for
void* malloc1() {
return(malloc1(1));
}
This FP seems to be common in daca results.
It also makes it possible to improve handling of casts, for example
cppcheck now warns about
void f() {
strcpy(a, (void*) strdup(p));
}
But not for
char* f() {
char* ret = (char*)strcpy(malloc(10), "abc");
return ret;
}
These FP/FN were introduced when the check was switched to use the
simplified token list.
