In certain cases, a 
note
icon appears to the right of the link in the Function
Name field. Hover over the note and a tooltip appears
that lists every special consideration that is applicable to this
link. Here is a list of all of the possible notes that can be found
in a call chains report:
The point at which execution for this profiling run began
The point at which execution for this profiling run ended
Function call data was merged into the ancestor link of this function due to unbounded recursion at this point
Function returned to an unexpected point
Execution resumed here after a return from an unexpected point
Synchronization was lost at this point during the run, due to trace or ETM overflows.
Thread Call Chain Root:
Name of ThreadException Call Chain Root:
Name of Exception
The call chains report includes two buttons in its toolbar
to help you navigate to each call chain link with an attached note.
Use the 
button
to go to the next call chain link with an attached note and the 
button
to go to the previous one. This selects the annotated call chain
link and expands the call chain to the level necessary to expose
it.
