Another observation, without knowing how helpful it may be: KDevelop is particularly crashy in my setup when I have recently created a new source file. The crashes do not always look like the one I posted above, in fact, I often just get a crash with obvious stack corruption, which makes this particularly painful to help to track down. However, after removing the DUChain cache and letting KDevelop re-parse everything, things are stable (or at least much more stable). Given the particular error uncovered by Valgrind in comment #12 - attempting to delete[] something far inside a block - it is tempting to suspect that the bug is related to how the DUChain items are migrated to and from the manual memory management, perhaps in combination with some "generic" memory error somewhere else. However, that code looks like not too well documented magic to me, so I have no idea where to even start. Is there a way to turn all that magic *off* completely? I understand that this might cost some performance, but it might help with (a) narrowing down the scope of the bug and (b) using Valgrind to track down any additional memory errors that may contribute to this bug. *** Bug 323329 has been marked as a duplicate of this bug. *** *** Bug 323999 has been marked as a duplicate of this bug. *** *** Bug 324764 has been marked as a duplicate of this bug. *** *** Bug 326359 has been marked as a duplicate of this bug. *** Could someone with code knowledge have a look into this?

Hello! We are working on a new clang-based C/C++ language plugin for KDevelop 5 which supersedes the old C++ plugin in KDevelop 4. See e.g.: https://www.kdevelop.org/news/first-beta-release-kdevelop-500-available Due to a lack of manpower, we cannot fix bugs in the old C++ plugin. We rather want to supply a good Clang based C++ experience for KDevelop 5 than wasting our time on the legacy C++ support for KDevelop 4. With the new clang-based C/C++ language plugin, the bug presented here does not occur. In my testing. For these reasons, I'll close this bug. Please stay tuned for KDevelop 5. If you think this bug is applicable to Clang/KDevelop 5, please reopen the report and add new information on how to reproduce the bug there. Sorry for the inconvenience, I hope you understand the reasoning above. Cheers |
