Missing End Task

Occurs when a task-begin annotation is executed but the corresponding task-end annotation is not executed before the site, thread, or application exits.
Problem type: Missing end task
ID
Code Location
Description
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.
void main() {     ANNOTATE_SITE_BEGIN(site_name);         ANNOTATE_TASK_BEGIN(taskname1);     ANNOTATE_SITE_END(); }
This example lacks an end-task annotation,
ANNOTATE_TASK_END()
.
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.
