Hello, when I was installing the Intel vtune amplifier 2016 update3 on windows7, I got a warning "System reboot may be required" and after rebooting my computer the warning still existed.I don't know how to resolve the problem, so I choose to ignore the warning and finished the installment.(ps. Antivirus sofware is turned off).
for Basic Hotspots analysis, after my application finishes, I get:
[Instrumentation Engine]: SYSCALL_INSPECTOR:Too long trace in the NTDLL!NtSetContexThread function Incompatible operating system or incompatible software installed on the system Pin is exiting due to fatal error
What can cause that?
Please provide below info to triage the issue:
1) re-run your application in windbg and attach result of disassembly command 'u ntdll!NtSetContextThread'
2) specify version info of the ntdll.dll
3) do you run the collection when AntiVirus SW is ON or OFF?
The reason could be that a 3rd-party SW (anti-virus?) intercepts stack sampling collector dynamic instrumentation of the ntdll.
