Custome patterns cause memory overflow

I have a custome .log file for which I wanna create highlight patterns. I played around and experience a memory overflow and extension manager crash, every time I use quantifiers in the regex pattern.

    "logFileHighlighter.customPatterns": [
        {
            "pattern": "test",
            "foreground": "#f0ff00",
            "background": "#000000"
            
        },
        {
            "pattern": "A*",
            "foreground": "#f0ff00",
            "background": "#000000"
            
        }
    ],

I use a small logfile with 50 lines for debug.

The extension manager gives me that:

I can see in the ressource manager that my RAM is growing until the extension manager crashes.

Am I using wrong Regex syntax or do I have too little RAM?

Thanks, I upgraded to 2.13.0 and can confirm it works as expected.

Btw, thanks for the extension, it makes reading my app’s log files so much easier with all my custom patterns.

@winfij, I decided to temporarily revert the package updates and republish the extension. Upgrading to 2.13.0 should make it work again. I don’t understand this problem so I’ll be careful when upgrading again and will test your pattern. It doesn’t seem to be a problem purely related to quantifiers either, some regex expressions work perfectly and others don’t. Very strange.
