            Bug ID: 396847
           Summary: kdev-clang: test_duchain-clang crashes on exit
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: rjvbertin at gmail.com
  Target Milestone: ---

Application: test_duchain-clang ()
 (Compiled from sources)
Qt Version: 5.9.6
Frameworks Version: 5.47.0
Operating System: Linux 4.14.23-ck1-mainline-core2-rjvb x86_64
Distribution: Ubuntu 14.04.5 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Running the plugins/clang/tests/test_duchain-clang autotest always ends with a
crash (on Mac and Linux) in DUChain::documentClosed(), most likely while
evaluating top->url() .

It would seem that the foreach() loop does not stop when it encounters a NULL
`top` variable; rewriting the expression to

if(top && top->url() == url)

prevents the crash.

The crash can be reproduced every time.

-- Backtrace:
Application: test_duchain-clang (test_duchain-clang), signal: Segmentation
