Description
Two LTP jobs have failed recently in a similar way while waiting for needle match.
https://openqa.suse.de/tests/6638157
https://openqa.suse.de/tests/6625293
The first job has some interesting output in autoinst-log.txt:

The other job does not show any obvious error in the log:

[2021-07-31T07:22:01.325 CEST] [debug] backend process exited: 0

Suggestion¶
- Reproduce locally
- Extend
t/01-test_needle.tto reproduce this case - Have the test create and destroy multiple needs in a loop
- Try using an optimized build for tinycv (e.g. via cmake argument
-DCMAKE_BUILD_TYPE=RelWithDebInfo, see https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html) if the problem is not reproducible - Provoke more threading in opencv
- Investigate memory-handling on the Perl side, passed to opencv, in baseclass (check os-autoinst readme)

I've been adding the regex but it doesn't look like we're running auto_review currently/anymore.
Luckily the stacktrace is still available so I've attached it. That's the unmangled version of the relevant thread:

Looks like Perl passed a bad pointer to the XS function for destroying the tinycv::Image object so its destructor passes a bad pointer to the destructor of the cv::Mat object.

- File stacktrace4 stacktrace4 added
There are 3 more stack traces, likely one of them corresponds to the 2nd job. So there are basically two crashes, one involving image_destroy and one involving image_search.
By the way, I haven't seen such stack traces before (e.g. when looking at backend stack traces for different crashes).
Updated by mkittler about 3 years ago
It also happened on openqaworker13 (backtrace with image_search) so it is not specific openqaworker10.

This test should run the relevant functions many times over and over again: https://github.com/Martchus/os-autoinst/pull/new/debug-segfault-2
However, so far I failed to reproduce the problem.
Since compiler warnings are often useful to find bugs I've been creating https://github.com/os-autoinst/os-autoinst/pull/1740. I couldn't find any clear problems, though.

Here's another similar job failure with a slightly different error in the log:

Strangely there's no coredump from the day this job ran on openqaworker10 where the job ran according to the database. However, there are several other coredumps which I've attached. Many have actually no tinycv.so-frames within the stack trace; not sure whether they might even be bugs in Perl. One backtrace contains an image_scale-frame which is new (so far I've only seen image_search and image_destroy). The TBB threads all look the same and unproblematic (so the issue that signal handlers are invoked in these threads doesn't seem to be re-occurring).
Updated by mkittler about 3 years ago
I extended my test which runs image functionality by a few other functions but still cannot reproduce the issue locally. I've also tested against OpenCV 3. I also still couldn't find anything wrong with our code. It could be improved here and there according to certain guidelines and to avoid certain warnings but there's nothing which should cause UB or memory corruption.
I'm currently running out of ideas.

I've been running https://github.com/Martchus/os-autoinst/pull/new/debug-segfault-2 in a Leap 15.2 container but still couldn't reproduce the issue.

During the daily 2021-08-31 we decided that we don't have a good idea how to fix the actual problem. I see the following alternatives:
- With the above information provided and assuming that "auto_review" handles automatic retriggering at least on o3+osd move the ticket out of the backlog and wait for further information. Please anyone who sees the issue again or has any additional information comment on the ticket
- Ensure that openQA has a proper reason in an incomplete job so that openQA can automatically retrigger, see https://github.com/os-autoinst/openQA/blob/master/etc/openqa/openqa.ini#L76
- Ask perl experts if they can read out something better from the stack trace
