Bug description

Hello guys,
I'm trying to connect to a SFTP server via the Laravel storage facade. The storage facade uses Flysystem, which itself uses the phpseclib package. I use the following versions:

laravel/framework 11.27.2
league/flysystem-sftp-v3 3.29.0
phpseclib/phpseclib 3.0.42

When I am trying to connect to the server I get a segmentation fault.

I have tested PHP 8.2.25, PHP 8.3.13 and 8.4.0RC3. On the CLI a get the segmentation fault and with FPM I get a 502 Bad Gateway.

I also tested PHP 8.3.12 (cli) from Brew. With the Brew built everything works as expected.

Steps to reproduce

$sftp = new \phpseclib3\Net\SFTP('host');
$sftp->login('user', 'pass');

Relevant log output

> php artisan sftp
zsh: segmentation fault

I just asked a co-worker to run my code with the apple silicon build. The silicon build has no problems with the phpseclib library.

Versions:

PHP 8.3 (8.3.12)
Herd 1.11.2
Sonoma 14.5
