Comment 1 Milian Wolff 2011-05-29 00:00:12 UTC

hm anyone an idea how this could happen? looking at the source this would mean a nullptr returned from applySpecialization ? which should not happen :-S

@tim: is this reproducible?

Comment 2 Milian Wolff 2011-06-02 21:48:23 UTC

waiting for info

Comment 3 tim blechmann 2011-06-03 17:49:13 UTC

haven't been able to reproduce it :/

Comment 4 Milian Wolff 2011-06-03 17:58:26 UTC

please reopen once you can trigger it again

Comment 5 tim blechmann 2011-06-03 18:03:49 UTC

thanks for resolving the bug

New crash information added by DrKonqi

kdevelop (4.2.2) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

When I was coding, KDevelop crashed, but I didn't look at the backtrace. Then whenever I start KDevelop again, it offers to recover one of my files that I was editing before. I decline the recovery because there is not really something to recover.
Whenever I start with adding a specific line of code to this file (entering 'typedef ' on a new line), KDevelop crashs after the space after typedef. I have been able to reproduce this crash three times using the same steps. After the third crash I have not tried again.
If there is something I can help with to analyze this bug, let me know.

Comment 7 Milian Wolff 2011-07-04 15:37:58 UTC

Git commit 089782fa06d2a685c2ff26b8907b786a207d1f9f by Milian Wolff.
Committed on 04/07/2011 at 17:36.
Pushed by mwolff into branch 'master'.

use context that is checked in the conditional instead of member var

this hopefully fixes a rare crash

also cleanup duplicate checks of owner

Comment 8 Milian Wolff 2011-07-04 15:43:51 UTC

please send us the file that triggers this crash and/or create a new minimal testcase along with detailed steps on what is required to trigger the crash.

C++ files triggering kdevelop project crash

The following triggers a kdevelop crash for me:
1. start a new session
2. open permlib/include/permlib/bsgs.h from the extracted tar.gz
3. go to line 104 (which is a blank line)
4. type: 'typedef ' as if adding a new typedef
After the space after typedef, kdevelop crashes for me reproducibly.

Comment 10 Milian Wolff 2011-07-08 14:26:52 UTC

works for me now with the latest patch. or is it still not working for you?

Comment 11 Thomas Rehn 2011-07-11 06:07:27 UTC

I've just compiled kdevelop from git, it does not crash any more on this bug. Thanks a lot!
