[kdevelop] [Bug 486932] Background parser crash C++ source
https://bugs.kde.org/show_bug.cgi?id=486932 Dan Leinir Turthra Jensen changed: What|Removed |Added CC||ad...@leinir.dk --- Comment #10 from Dan Leinir Turthra Jensen --- Just adding my two eurocents to the thing, to say that i also got this while adding an #include. It does not happen fully consistently, but maybe every other time i try and add one (feels like more regularly than that, but that's probably more because i only really notice when i have to restart the program).

https://bugs.kde.org/show_bug.cgi?id=486932 --- Comment #6 from Igor Kushnir --- My previous comment missed preliminary coredumpctl steps: 0.1. coredumpctl list kdevelop --since 2024-05-19. 0.2. Locate the necessary entry in the printed table and show its details via `coredumpctl info 151255` (where 151255 is the PID of the entry). 0.3. Find the Storage line in the info output, e.g. "Storage: /var/lib/systemd/coredump/core.kdevelop.1000.df23a15637fe47fbae399826251ac233.151255.171613318900.zst (present)" and extract the .zst archive to obtain the actual debuggable core dump file. Oh, and after these steps KDevelop's Frame Stack tool view also shows the backtrace with debug symbols. libclang headers can be opened and examined from the IDE right away. To examine libclang source files as well: 8. Download clang sources. I got the clang repository already, so just `git fetch origin` and `git checkout llvmorg-17.0.6` to match my system clang package version. 9. In the GDB tool view: set substitute-path /usr/src/debug/clang/clang-17.0.6.src /path/to/llvm-project/clang 10. Activate the Frame Stack tool view and switch to another thread, then back, to open libclang source files by clicking their lines in the backtrace. -- You are receiving this mail because: You are watching all bug changes.

--- Comment #5 from Igor Kushnir ---
(In reply to Igor Kushnir from comment #4)
> The crash just happened once to me. But I cannot reproduce it. Here is a
> more detailed backtrace (still no libclang debug symbols):
Managed to obtain a complete backtrace for the single crash that happened on my
system. Here are the steps in case I or someone else needs them in the future
(they can also be used to examine past core dumps with freshly downloaded
KDevelop debug symbols).
1. Download debuginfod debug symbols for libclang:
$ debuginfod-find debuginfo /usr/lib/libclang.so.17
/home/igor/.cache/debuginfod_client/02120dc8526595aac7ab8bc78eca4efc936b09be/debuginfo
2. Trigger the "Run=>Examine Core File=>Examine Core File with GDB" action in
KDevelop, select /bin/kdevelop and the crash coredump in the dialog that
appears.
3. Activate KDevelop's GDB tool view. All commands in the following steps are
entered into the GDB command line edit inside this tool view.
4. At this point the command `thread apply 15 bt` still shows a backtrace
without libclang debug symbols. Read and follow the top answer here:

I have had KDevelop crashing this way for about a month, and the backtrace is from KDevelop's project (via GDB). I have seen it crash even before completing "#include". > Yes, please use `options=(!strip)` and `-DCMAKE_BUILD_TYPE=RelWithDebInfo`. I think I'll rebuild just to re-produce the bt and try print the locals just before descending into clang code. However, clang would be painful to build in this mode.. last time I did it the install directory was +10GiB o__O I did have an idea for parser blacklist: if the text line is found from it, the code completion would not be triggered until the typed text is longer than best matching black list entry. This could perhaps allow the user (temporally) dealing with cases where the parser might crash on incomplete code, or just being too annoying. For example, it doesn't make sense to start trying to suggest anything at "#include " for me, as the next two characters would greatly shrink the possibilities, and even suggesting anything at "#include <" is kind of just irritating. I know an such blacklist entry would prevent completing the "#include" keyword, but I would like to suppress a such the code completion anyway. -- You are receiving this mail because: You are watching all bug changes.

Though I suspect the bug is in libclang, in which case libclang debug symbols will be needed. -- You are receiving this mail because: You are watching all bug changes.
