Description likeit.mp 2017-12-25 08:36:13 UTC

Application: kdevelop (5.2.1)

Qt Version: 5.10.0
Frameworks Version: 5.41.0
Operating System: Linux 4.14.8-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

Example:

class Example
{
public:
  const std::string header;
};

Now I create an an object from this Example class.

auto* obj = new Example(...)

Now I try to access the header variable in the code (in some other source files):

obj->... 

The code completion now shows me the header variable, if I press Enter to select the variable (header)
KDevelop crash every time. 

I use ArchLinux with the latest KDevelop version 5.2.1.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault

Comment 1 Sven Brauch 2017-12-25 09:31:01 UTC

Hm, unsurprisingly not reproducible here (the example is very simple and if this would crash in general, we would crash like all the time). If this is indeed a reproducible issue, it probably has something to do with your project's file layout or the concrete type in question. Which project do you have open?

Comment 2 likeit.mp 2017-12-25 12:55:52 UTC

Created attachment 109508 [details]
KDevelop Example Project

Comment 3 likeit.mp 2017-12-25 13:27:12 UTC

For my project I use CMAKE & QT with C++14 (see attachments / CMakeLists.txt).

The structure is the same as in the main project.

src/world.cpp:

There is a simple function say_hello(...), if I write

if (hello->... 

select the member-variable and KDevelop has crashed always. This happens 20 times (yesterday and today) always in the same line.

Today I have started KDevelop with GDB -> crashed after variable selection:

This was the last GDB output:
usr/lib/libKDevPlatformLanguage.so.52 FunctionType::returnType() const

Then I execute KDevelop with GDB again it works without any problems?

Comment 4 Justin Zobel 2020-12-17 05:33:48 UTC

Thank you for the crash report.
