Description Daniel Stöckel 2016-06-04 09:38:25 UTC

Application: kdevelop (4.90.92)

Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.5.4-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

I ran a set of unit tests via the CTest toolview. Some warnings about CTest instances already running popped up, which I clicked away. Shortly after, KDevelop crashed. Since then, whenever I start KDevelop it crashes after a short period of time. 

The crash always seems to occur at the same location as in this backtrace. Removing the session under .local/share/kdevelop/sessions did not change anything.

- Versions
I am using the current master branch of both, kdevelop and kdevplatform. The commit ids are:
kdevelop: 3d7d2dc59ed8
kdevplatform: 83349684134

This is running on a fully updated Arch Linux (KDE Frameworks 5.22.0, Qt 5.6.0, Plasma 5.6)

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Comment 1 Daniel Stöckel 2016-06-05 10:30:00 UTC

Created attachment 99380 [details]
Skip CMake functions without arguments.

The problem seems to be that the startVisiting method of DeclarationBuilder assumes that there is always an argument to a CMake function. This seems to be wrong in some instances. The attached patch fixes the crash for me, but I am not sure whether it is the right thing to do here.

Comment 3 Daniel Stöckel 2016-06-09 20:44:23 UTC

It looks like #363943 is a duplicate of this bug.

Comment 4 Kevin Funk 2016-06-10 11:55:56 UTC

*** Bug 363943 has been marked as a duplicate of this bug. ***

Comment 5 Eugene Shalygin 2016-06-10 12:04:36 UTC

For me it crashes on `macro (MACRO_OPTIONAL_FIND_PACKAGE _name )` which does have arguments, but func.arguments list is empty in the DeclarationBuilder::startVisiting(). A similar patch saves me from crashes, but cmake parsing seems to be incomplete, because completion does not work in some cmake files now.

Comment 6 Andreas Cord-Landwehr 2016-06-15 09:07:44 UTC

Daniel, can you retest with current master? The cmake parsing crash should be fixed with b4263571146bab54459dd0aa122fc5dc604705d5. If not, please feel free to re-open.

Comment 7 Daniel Stöckel 2016-06-16 18:08:39 UTC

I can no longer reproduce the crash. Thank you for fixing this!

Comment 8 Eugene Shalygin 2016-06-16 18:17:56 UTC

I still want to know how
macro (MACRO_OPTIONAL_FIND_PACKAGE _name ) (see my description in #363943)
is considered to be a macro without parameters?
