swoole/library incompatibility ?

[emmanuelGuiton]

I created a simple Composer project that only depends on swoole/library and Psalm in a dev dependency. Running any Psalm command results in a crash such as

$ ./vendor/bin/psalm --init
Calculating best config level based on project files
Uncaught RuntimeException: PHP Error: Constant SWOOLE_LIBRARY already defined in ~/test/vendor/swoole/library/src/constants.php:12 for command with CLI args "./vendor/bin/psalm --init" in ~/test/vendor/vimeo/psalm/src/Psalm/Internal/ErrorHandler.php:76

(Psalm (unknown version) crashed due to an uncaught Throwable)

Note that I have the swoole extension installed and loaded with the parameter swoole.enable_library=off. Same result if I use psalm/phar instead of vimeo/psalm.

However, I do have some other, more complex, projects depending on swoole/library for which using psalm/phar works (and vimeo/psalm does not) ... I am a bit puzzled.

The composer file :

{
	"name": "test/psalm-swoole",
	"description": "Psalm / Swoole test.",
	"version": "0.1",
	"require": {
		"ext-swoole": "*",
		"swoole/library": "6.0.*"
	},
	"require-dev": {
		"vimeo/psalm": "6.4.*"
	},
	"autoload": {
		"psr-4": {
			"Test\\": "sources/"
		}
	},
	"config": {
		"vendor-dir": "vendor",
		"optimize-autoloader": true
	}
}

Hey @emmanuelGuiton, can you reproduce the issue on https://psalm.dev? These will be used as phpunit tests when implementing the feature or fixing this bug.

With Psalm 6.13.* and PHP 8.4.*, the issue still exists but the symptoms have changed.
