Merge pull request #2703 from rikardfalkeborn/9652-fp-function-call-cast-config
Fix #9652 (fp memleak with function call with cast)
2020-07-08 15:10:41 +02:00
Rikard Falkeborn 4996ec190e Fix #9652 (fp memleak with function call with cast)
When the first argument was (void *)(1), at the start of the second
iteration, arg was pointing to the "1", which caused problems for
nextArgument(), which saw the ")" as the next token and returned
nullptr, signalling that there are no more arguments.

Instead, save the first token in the argument, which makes
nextArgument() do the right thing.

Rikard Falkeborn d5345052ab Fix #9793 (false positive, memleak with lambda)
Skip scopes with lambdas (similar to how checkleakautovar does). In
order to fix this when the lambda is inside a for loop, make
hasInlineOrLambdaFunction() recursive. This should be what all existing
users want.

Ken-Patrick Lehrmann 5a3789a23f 9769: Improve value flow for ternary operator
In some cases, the condition of the ternary operator is assigned a known
value after the two possible results, and in such cases, we would not
take the opportunity to assign a value to the ternary operator (and to
the other parents in the ast).
This patch adds this capability.

9768: Fix ast with throw in the middle of return (#2678)
* 9768: Fix ast with throw in the middle of return

```
int f(bool x)
{
    return x ? 0 : throw 0;
}
```

The `throw` part was not included in the ast, leading to an invalid
ternary operator.

* 8526: Fix ast construction for ternary operator

This tries to decide a bit more properly when ':' can be part of a
ternary operator. More precisely, there are some times when we want to
delay the construction of the ast for ':', so that it is place
accordingly to the matching '?'.

Typically, this fixes an issue with
`return val < 0 ? throw 1 : val;`,
where the ast for ':' would be constructed during as part of the
`throw`, and the ast for `?` would be invalid.

This patch is a bit of a hardcode, stating that we don't expect ':'
inside a throw, unless there is a complete ternary operator in there
(there can't be a range based for loop, a case in a switch). When we
reach ':', we know we are and the end of the `throw`.
