1. Install local docker-compose up -d
2. Enter on fpm_xdebug container
3. Exec php -i

Expected result

Actual result

1. Segmentation fault (core dumped)
   

[vacla]

I can reproduce it.

[kevin-mitchell]

I believe I am experiencing this same issue, though specifically what I'm seeing is that when I set the appropriate debug cookies / headers in a browser at attempt to debug I'm seeing 502 errors in the browser and SIGSEGV in the fpm_xdebug container:

[willryan-stemcell]

I believe this is the same issue as #366

[mfauvell]

I can reproduce it with version 1.4.0 of images.

[jeromecx]

I can confirm this issue also occurs with the following images:

• magento/magento-cloud-docker-php:8.4-cli-1.4.2
• magento/magento-cloud-docker-php:8.3-cli-1.4.2
• magento/magento-cloud-docker-php:8.3-cli-1.4.1

The segfault is reproducible with php -i as soon as Xdebug is loaded.
