Description Milian Wolff 2019-01-29 11:49:39 UTC 
Application: kdevelop (5.3.40)
 (Compiled from sources)
Qt Version: 5.12.0
Frameworks Version: 5.54.0
Operating System: Linux 4.20.4-arch1-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
I edited text and then KDevelop (or, well Katepart) crashed. I see this regularly, but couldn't find an easy way to reproduce this.

Assert message was:

terminate called after throwing an instance of 'std::out_of_range'
  what():  vector::_M_range_check: __n (which is 173) >= this->size() (which is 79)

I initially believed it's due to code folding which messes up the line query somewhere, but this last file of mine wasn't folded at all (had no initial comment auto-folded block at the start e.g.). Is it maybe due to the "scroll below last line" feature?

-- Backtrace:

Comment 1 Christoph Cullmann 2019-07-13 20:00:44 UTC 
Hmm, I have taken a look at the code, don't really see how there the line index could be wrong :/ Did you get any idea how to reproduce this?
Comment 2 Milian Wolff 2019-07-16 20:22:32 UTC 
no :(
Comment 3 Christoph Cullmann 2019-07-16 20:24:09 UTC 
Too bad :(
Comment 4 Christoph Cullmann 2019-08-24 15:44:43 UTC 
Then we can close this until one has some idea how to reproduce.
I inspected the code, I see no obvious fault.
