Profiled program fails to write files

I am a newbie using vtune

I am trying to profile a portion of Quantum Espresso (http://www.quantum-espresso.org/) 

However, when run under (or attached to) VTune gui, program raises a file handling error signal (38) and crashes. The program runs normally otherwise.  

I have tried AMPLXE_RUNTOOL_OPTIONS="--profiling-signal <another signal>" where another signal is 16, 39 etc. however, this did not resolve the situation.

What might be going wrong?

Baris, do you use Hotspots analysis type? Does it happen with Advanced Hotspots (with/without stacks)?

Which VTune version do you use?

Hi, 

I am using the basic hotspot analysis. 

The program fails writing a file to the disk, citing a signal 38 was caught (although I am using a different profiling signal as mentioned above)

Details attached. 

Thanks!

Update: Apparently it is not a file written to a disk this time.
