CreateTask in Task group with Unobserved function call fails #71

Open GoogleCodeExporter opened 9 years ago

Following code produces on certain machines an error. The error happens 
sometimes but not all the times.

    TaskGroup := CreateTaskGroup;
    try
      for I := 0 to 2 do
        CreateTask (TestTask, Format ('TestTask %d', [I]))
          .SetParameter ('Number', I)
          .Unbserved
          .Join (TaskGroup);

      TaskGroup.RunAll;

Starting the tasks inside the Task Group Fails with the following stack trace:

What version of the product are you using? On what operating system?

Using Version 3.03b on an Windows Server 2008R2 64bit.

Please provide any additional information below.

Removing the Unobserved function call works for us!
