The following program runs for about 45s (even though I've set the timeout interval to 2s) before finally throwing the OutOfMemoryException. You have to run in on .NET Framework 4.7.2 to reproduce it (this code hangs permanently on .NET Core, which I think is due to an issue in .NET Core itself).
using System;
namespace Jint.Run
{
public class Program
{
public static void Main(string[] args)
{
new Engine(SetOptions).Execute("'x'.match(/|/g);");
}
private static void SetOptions(Options options)
{
options.LimitRecursion(32).TimeoutInterval(TimeSpan.FromSeconds(2));
}
}
}
Here are the exception details:
System.OutOfMemoryException
HResult=0x8007000E
Message=Array dimensions exceeded supported range.
