Summary0001490: Segfault on PHP 7.2 + 2.6.0-dev in Travis CI

Since today one of our CI builds on Travis started segfaulting consistently. Unfortunately I cannot reproduce it locally, but on Travis it is consistent. All other versions work so it seems to be Xdebug 2.6.0-dev with PHP 7.2RC6 related. Tests work with vanilla 7.2RC6.

Steps To Reproduce

See, all code and commands are there.

Following should work with 7.2RC6 +

git clone

TagsNo tags attached.
Operating System
PHP Version7.2-dev

Mantis is incorrectly joining a comma in the link, it is

I tried reproducing this with:

$ git clone
$ cd datatables-bundle/
$ php ~/composer.phar install
$ ./vendor/bin/phpunit

But I get an application error:

Fatal error: Uncaught Error: Class 'Tests\Fixtures\AppKernel' not found in /tmp/datatables-bundle/tests/phpunit-bootstrap.php on line 26

Error: Class 'Tests\Fixtures\AppKernel' not found in /tmp/datatables-bundle/tests/phpunit-bootstrap.php on line 26

Please provide steps so that I can at least run the tests.

Annoyingly, it seems that running the tests, also made it remove its own directory:

derick@singlemalt:/tmp/datatables-bundle $ ls
sh: 0: getcwd() failed: No such file or directory
sh: 0: getcwd() failed: No such file or directory
[GIT: (HEAD)][PHP: 7.2.0-dev ]
derick@singlemalt:/tmp/datatables-bundle $ cd ..
[PHP: 7.2.0-dev ]
derick@singlemalt:/tmp $ cd -
bash: cd: /tmp/datatables-bundle: No such file or directory

I will not be running these tests again, unless I have a small reproducible case and not something that downloads 4MB of code through composer.

My apologies, you have run into the most obscure edge case - the tests use /tmp/datatables-bundle for stateful temporary storage, and clean them up during bootstrap. So that's just about the only folder the tests can't work from.

If you clone into a different folder it'll work fine.

Fixed the dependency on global test folders:

Issue still reproduces:

I could indeed reproduce the segfault with an old Xdebug 2.6.0-dev, but not with the one from last night. I expect this to be a duplicate of 0001486, which I believe fixes this problem.

Thank you, I will leave the tests at allow_fail and monitor whether they are automatically fixed the coming week.
