Summary0002078: PHP with XDebug throw segmentation faults when running tests
Description

Hi, The other day we faced a wired segmentation fault when running the test in pipeline.
The bug is something like https://bugs.xdebug.org/view.php?id=1965 bug. and it crashesh exactly on the same line.
The bug really hard to regenerate and it's totally random. sometimes is working fine and sometimes out of the blue gets the segmentation fault.
I tried to trace with xdebug to see what line exactly causes the seg fault but when trace mode is enabled it works fine.
I tried with diffrent version of xdebug but including github master version but I got seg fault again.
I tried to update mongodb driver same.
I managed to get the full bt using gdb and getting valgrind's output. but i cannot provide an script to reproduce the bug. because our code stack is really bug and I cannot regenerate the same error using an small script. but I hope you can get some ideas using gdb output and valgrind.

Can you please upgrade to the latest Xdebug version (3.1.3), and see if that addresses the problem? I have fixed several crash bugs since 3.0.4.

I have already tested it with 3.1.3 also, I even tested with master branch and 3_1 branch but still crashes.

Can you please provide a short reproducible script in that case?

unfortunately because it's totally random and our code stack is quite complicated I cannot regenerate it. each time it happens in a different test case.

Sorry, but I don't have enough information here to do anything about this. It seems to have to do something with generators, but without a reproducible case I can do little. Are you sure you can't make one?

Hi derick, I tried to reproduce it but unfortunately because it's totally random, I couldn't reproduce it in with a small code

I still can't reproduce this, and there has not been more information. As I haven't seen any other bug reports that are similar, I am therefore closing this issue.
