Hi

https://software.intel.com/en-us/vtune-cookbook-profiling-linux-and-qnx-system-boot-time#QNX

with Inter VTUNE user guide above on QNX, I want to get more datas necessary for analyzing processes running in target board with VTUNE Profiler. However, I found that  segmentation fault error happens in target board when typing "./sep -p2" to send call-stack datas to host PC.

 (refer to attached picture)

Environment of target board is with Intel Denverton and operating system QNX. 

Environment of Host PC is with windows 7 and VTUNE Amplifier 2019 Update7

But, If executing sep without any options in target board , It works well. (ex typing only "./sep" and enter). and VTUNE Profiler can get datas from target board. (but there are not call-stack datas because not adding "-p2" 

Why is the segfault error made when with QNX environment?

Best Regards

Unfortunately this is a known problem with QNX 7 and the -p option, and it is not planned to be supported in the near future.
