インテル® VTune™ Amplifier 2018 ヘルプ
VTune Amplifier displays [Guessed stack frame(s)] in the grid panes.
VTune Amplifier did not unwind the stack to reduce data collection overhead, but resolved the stack heuristically.
[Guessed stack frame] is considered to be a system function. If the Call Stack Mode filter bar option is set to User/system functions, the VTune Amplifier displays [Guessed stack frame(s)].
To avoid displaying [Guessed stack frame(s)], set the Call Stack Mode filter bar option to Only user functions.
