Occurs when a task-begin annotation is executed but the corresponding task-end annotation is not executed before the site, thread, or application exits.

1 |
Task start |
Represents the location and associated call stack when the task began execution. |
|
2 |
Parallel site |
If present, represents the location and associated call stack of the beginning of the parallel site that contained the task. |
Example
void main()
{
ANNOTATE_SITE_BEGIN(site_name);
ANNOTATE_TASK_BEGIN(taskname1);
ANNOTATE_SITE_END();
}
This example lacks an end-task annotation, ANNOTATE_TASK_END().
Note
An error also occurs if your code branches around a single ANNOTATE_TASK_END() annotation.
Possible Correction Strategies
Always execute an ANNOTATE_TASK_BEGIN(taskname) annotation before executing an ANNOTATE_SITE_END() annotation. This omission can be caused by throw exceptions, return, break, continue, and goto statements or keywords. All control flow paths out of a site need to use the ANNOTATE_TASK_END() annotations.
