Segmentation fault (core dumped)

When I tried throw Exception I catch: Segmentation fault(core dump)

For example on "sentry/sentry": "^2.0" and "sentry/sentry-laravel": "1.2.0" I catch these errors:

Segmentation fault (core dumped)

For example on "sentry/sentry": "2.2.5" and "sentry/sentry-laravel": "1.5.0" I catch only: Segmentation fault (core dumped)

I don't know what happened maybe somebody caught this and resolved?

Upd: While It's only in scheme migration:

class AddIndexToUsers extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::table('users', function (Blueprint $table) {
            $table->index('id');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::table('users', function (Blueprint $table) {
            $table->dropIndex([
                'id',
                'wront_value'
            ]);
        });
    }
}

Here I included wrong index and after it I caught Segmentation fault Upd: PHP Version: 7.4

[stayallive]

Hmm, could you also share the exact version of PHP you are using when the segmentation fault occurred?

[acrossoffwest]

@stayallive 7.4

[sidvanvliet]

I am experiencing the same issue.

[stayallive]

@acrossoffwest are you able to consistently trigger this using the php artisan migrate:rollback command?

When trying your composer.json I am unable to trigger this on OS X (with your composer requirements and just a clean Lumen with Sentry configured):

PHP 7.4.0 (cli) (built: Nov 29 2019 16:18:44) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.0, Copyright (c), by Zend Technologies

@sidvanvliet are you also on Lumen and PHP 7.4? Could you share your composer.json.

Could you both tell me a bit more about the machine you are running into this like the OS & output from php -v?

---

Edit: Sharing your bootstrap/app.php could also help to see what's enabled / configured that might be able to cause the event leading to the segfault.

[sidvanvliet]

@stayallive I am using using Laravel Framework 6.4 with PHP 7.4.0 on a MacBook Pro running version 10.15 (Catalina)

Here is the php -v output:

And my bootstrap/app.php looks like this (default):

<?php

$app = new Illuminate\Foundation\Application(
    $_ENV['APP_BASE_PATH'] ?? dirname(__DIR__)
);

/*

*/

$app->singleton(
    Illuminate\Contracts\Http\Kernel::class,
    App\Http\Kernel::class
);

$app->singleton(
    Illuminate\Contracts\Console\Kernel::class,
    App\Console\Kernel::class

$app->singleton(

    App\Exceptions\Handler::class

/*

*/

return $app;

@sidvanvliet ah, I wondered why your bootstrap/app.php looked like that but as you said you are on the full framework, in that case it's not relevant but thanks for sharing :)

Can you also share what exactly you do or what happens in your app when the segfault occurs?

[acrossoffwest]

And one more moment I'm using Docker with image: php:7.4.0-fpm-buster

[sidvanvliet]

@stayallive It happened when a job failed.

[stayallive]

Can any of you two share or extract a reliable reproduction out of where it fails for you because I'm unable to make it happen still.

My best guess is this is a 7.4 bug and is triggered by our error tracking or trying to access something from the shutdown function (wouldn't be the first time) but it's extremely tricky to find a reproduction so we can try and figure out if we can fix this.

[acrossoffwest]

I tried to repeat this issue on new lumen project and it worked fine.

[stayallive]

If by any chance you run into it again please do let us know if you have more info so we can investigate further!
