Bug ID: 418220
Summary: crash on libclang parsing
Product: kdevelop
Version: 5.5.0
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org
Reporter: koncek.mar...@gmail.com
Target Milestone: ---

Source file that causes the crash
Description of problem:
Kdevelop crashes when parsing C++ code using libclang.
Version-Release number of selected component (if applicable):
kdevelop-5.5.0-1.fc31.src.rpm
clang-9.0.0-1.fc31.src.rpm
How reproducible:
In KDevelop create an empty .cpp file and #include the attached .hpp file.
KDevelop then crashes.
Additional info:
In my case if I have the same code directly in .cpp file it does not crash (but
I have disabled background parsing, but KDevelop does parse code when switching
tabs).
###
imporant lines: 19-30 of the provided source file.
Currently clang does not compile code that uses "auto&" as parameters.
Note that i am using "auto&" as function parameters on other places within
KDevelop and although it doesn't like them, most of the code is parsed anyway.
The crash does not happen when:
1) changing the auto& parameter for a proper template typename parameter as in:
template<typename Self>
static auto static_find(Self& self, const Key_type& key)
2) replacing the structured binding for a single variable initialization.
