Qt Version: 4.8.7
Operating System: Darwin 13.4.0 x86_64
Distribution (Platform): MacPorts Packages

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

I opened a session containing several projects, one I closed successfully yesterday. 51% into reparsing the code I got the crash and attached backtrace (thread 9 is the culprit), and saw this on the calling terminal:

Comment 1 Milian Wolff 2015-11-24 17:06:45 UTC

What line did it crash in?

    frame #4: 0x0000000128a54598 libkdev4cppduchain.dylib`DeclarationBuilder::closeDeclaration(bool) + 1800


what is this supposed to mean? Can you translate that to an easier-to-understand GDB-like backtrace with file:line information?

Also, it may quite likely be closed as wontfix anyway as we are spending our time on kdev-clang nowadays. If it's an easy fix we may want to fix it for 4.7 though.

Comment 2 RJVB 2015-11-24 19:07:05 UTC

I'm afraid gdb hasn't worked properly on OS X for years now (didn't you know that?), but if I remember (and find a moment) to rebuild kdevelop without LTO I should get line numbers.

I thought the

"__list_imp< _Tp, _Alloc >" "__list_imp< _Tp, _Alloc >"

output came from an ASSERT or something like that, but you're right, I see neither "abort" nor "qFatal" in the backtrace.

Comment 3 Michał Walenciak 2015-11-24 19:45:04 UTC

Comment 4 RJVB 2015-11-25 15:37:09 UTC

That certainly looks like the same crash to me.

For me, this crash only happens when KDevelop is parsing a bunch of projects after opening a session (and apparently preferably when the session contains many projects). I don't think it ever happened when the parser reparsed an open file after modification.

If it's impossible to resolve the underlying issue, a workaround could then be to 
1) defer parsing to after all projects are loaded completely
2) make the automatic start of the parser optional, and provide a way (button, menu action) to trigger the parsing of an entire project manually.

Option 1) would be probably less sure as a workaround.

Option 2) can currently be approximated by deactivating the parser altogether, then you lose all benefits of code parsing -- AFAIK deactivation will also discard all cached parsing information.

I also still don't understand why it is necessary to parse a file when it hasn't changed since the last parsing step. Why not simply load the cached information, and only trigger the parser when the file changes (either in the embedded editor or when a timestamp and/or hash/CRC mismatch is detected)?

kdevelop (4.7.2) on KDE Platform 4.14.14 using Qt 4.8.7

- What I was doing when the application crashed:

Same story: crash after opening a session with multiple project, during the initial (re)parse that cannot be avoided if you want to benefit from parsing information at all.

Comment 6 Kevin Funk 2015-11-27 17:57:35 UTC

@Michal: Which project is this? Is the crash always reproducible?

Confirming b/c of multiple reports.

Comment 7 Michał Walenciak 2015-11-29 13:06:39 UTC

@Kevin: I used to have it every time, but now it's more random. But as far as I can see it is reproducible every time I remove ~/.cache/kdevduchain

Here's the project:
https://github.com/Kicer86/photobroom

Comment 8 Kevin Funk 2015-11-29 14:37:42 UTC

For the record: Can't reproduce on Linux.

Comment 9 Michał Walenciak 2015-11-29 14:41:35 UTC

@Kevin: If you want I can compile kdevelop with some patch or extra options If you need more information.

Comment 10 Milian Wolff 2015-12-01 17:35:07 UTC

Do you remove the cache while kdevelop is running?

Comment 11 RJVB 2015-12-01 20:36:43 UTC

No, not I, at least not that I know of ...

Comment 12 Michał Walenciak 2015-12-03 19:42:11 UTC

@Milian Wolff: I did it before starting KDevelop. My KDevelop was crashing every time, but then it somehow dealt with the problem and was not crashing anymore (I guess cache had all the data so there was no need to parse all files again). To reproduce the problem again I had to remove cache.

Comment 13 Milian Wolff 2015-12-04 18:04:08 UTC

Well, without a way for me to reproduce this, I'm tempted to close this as UNMAINTAINED, as it only affects our old C++ parser. With kdev-clang / KDevelop 5, this issue should not occur anymore...

Git commit f78c39655cb3d5dacca43fde60c7e748efb10820 by Milian Wolff.
Committed on 21/01/2016 at 12:41.
Pushed by mwolff into branch '4.7'.

Don't access declaration without holding the DUChain lock.

This hopefully fixes a crash in the declaration builder.
