Phalcon 5.4 Installation via PECL Fails on PHP 7.4

[m-cisse-easy-live]

Description:

I am attempting to install Phalcon 5.4 on a server with 2GB RAM using PHP 7.4, following the official documentation: [Phalcon 5.4 Upgrade Guide](https://docs.phalcon.io/5.4/upgrade/).

When running the installation via PECL using the command:

pecl install phalcon-5.4.0

The process halts with the following logs:

After this step, the installation freezes indefinitely.

Steps to Reproduce:

1. Use a 2GB RAM server with PHP 7.4 installed.
2. Follow the installation steps from the Phalcon 5.4 documentation.
3. Run:

   pecl install phalcon-5.4.0

4. Observe that the installation does not complete.

What I Tried:

• Noticed in the Phalcon documentation that at least 4GB of RAM is recommended.
• Configured a 5GB swap file on the server to compensate.
• Despite this, the installation still fails.

Expected Behavior:

Phalcon should install successfully without freezing.

Actual Behavior:

The installation process gets stuck after displaying multiple warnings and compilation messages.

System Information:

• PHP Version: 7.4
• Phalcon Version: 5.4.0
• RAM: 2GB (with additional 5GB swap)
• OS: Linux Debian 11

Additional Notes:

• Is this issue related to insufficient RAM, despite the swap configuration?
• Could the warnings about pointer incompatibility and memory operations indicate a compatibility issue with PHP 7.4?
• Any suggestions on how to resolve or debug this further?
