Mojave 10.14.5 and homebrew PHP not working properly

I'm trying to install PHP 7.(2|3) with Homebrew on Mojave 10.14.5 and I can't get it to work.

Fresh install of Mojave with only :

• Google Chrome
• Iterm
• Zsh
• Oh My Zsh

Right after Mojave is installed I run the following in my terminal :

• Install Homebrew (command line from the official website)
• brew install composer
• brew install php
• composer global require laravel/installer (composer is in the path)
• laravel new blog

It ends up with a segmentation fault :

[1] 9310 segmentation fault laravel new blog

I tried to reboot, uninstall and reinstall PHP/Homebrew/Mojave several times. I always ends up with the same error.

Also tried with php@7.2 and php@7.1 and other packages like wp-cli, it's the same.

I'm desperate, please help.

EDIT WITH MORE INFO :
