Description Jan-Matthias Braun 2019-11-26 11:31:02 UTC

Application: kdevelop (5.4.40)

Qt Version: 5.14.0
Frameworks Version: 5.64.0
Operating System: Linux 5.4.0 x86_64
Distribution: "Gentoo Base System release 2.6"

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

In a document with a syntactically wrong line, I was inserting one line above the syntactically wrong line.
Then kdevelop crashed.

The crash does not seem to be reproducible.

-- Backtrace (Reduced):

Comment 2 Francis Herne 2020-08-19 00:22:02 UTC

Unfortunately I don't think this can be traced without some reproducible example.

Clearly the relevant `Declaration*` is bogus, but it was just retrieved from the DUChain at this point -- the bug is in whichever code inserted it, and that can't be identified from the backtrace.

Please feel free to reopen if this recurs.

Comment 3 Francis Herne 2020-08-22 01:35:13 UTC

...of course, I say that, and then get a suspiciously-similar ASAN failure:

Comment 7 Sven Brauch 2023-01-23 10:12:06 UTC

@Francis: Is the ASAN trace reproducible? In that case, we should leave this open and investigate at some point.

Comment 8 Francis Herne 2023-01-23 14:07:41 UTC

I haven't seen this again.

To the original reporter (or anyone else): please reopen or file a new bug if you find a similar case that's reproducible.
