Description Guillaume Racicot 2018-05-09 18:52:05 UTC

Application: kdevelop (5.2.40)

Qt Version: 5.10.1
Frameworks Version: 5.45.0
Operating System: Linux 4.16.6-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:

Typing a character, invoking autocompletion.

It doesn't happen for any templates, but when using a particular set of templates it crashes every time.

I implemented the `is_detected` idiom and it triggered the bug.

This code makes it crash for me:

    #include <type_traits>

    template<typename...>
    struct voider {
        using type = void;
    };

    template<typename... Ts>
    using void_t = typename voider<Ts...>::type;

    namespace detail {

    template <typename Default, typename AlwaysVoid, template<typename...> class Op, typename... Args>
    struct detector {
        using value_t = std::false_type;
        using type = Default;
    };

    template <typename Default, template<typename...> class Op, typename... Args>
    struct detector<Default, void_t<Op<Args...>>, Op, Args...> {
        using value_t = std::true_type;
        using type = Op<Args...>;
    };

    } // namespace detail
        // <--- there

When tying a character just before the comment saying `there`, kdevelop crashes. I use the current master branch

The crash can be reproduced every time.

Comment 1 Friedrich W. H. Kossebau 2018-07-20 10:39:20 UTC

Git commit 6df7ff9882516f83883c811e7660a185c2e5727c by Friedrich W. H. Kossebau.
Committed on 20/07/2018 at 10:39.
Pushed by kossebau into branch 'master'.

Fix QStringBuilder taking reference to temporary due to auto

Summary:
Compiler decides for "auto" type result to use QStringBuilder, though the
expression passed to it includes a temporary QString result from a
QStringList::join() result. Which then is dropped after the assignement, due
to getting out of scope.
