Laravel update from 5.1.46 to 5.2.* php artisan Segmentation fault

I'm working to update a Laravel project from 5.1.46 to 5.2.*. After I followed the steps from here https://laravel.com/docs/5.2/upgrade#upgrade-5.2.0 I have ran the command

./composer.phar update

I receive the follow error when the composer tries to run

php artisan clear-compiled

Segmentation fault (core dumped)

I tried to run manually the command

php artisan clear-compiled -vvv

But I have exactly the same output. Do you have any idea how can I debug what is causes this? This appears with PHP 5.6. Also I've tried to use PHP 7.4, but it looks like the computer runs out of memory. For some reason the artisan is taking the entire memory of the computer, until the computer freezes.

Thanks!
