We have to use --profiling-signal=33 and --no-altstack because we experienced the same issue as https://software.intel.com/en-us/node/676061

Vladimir_R_Intel · ‎03-26-2018

Hi Zoy,

currently VTune Amplifier doesn't support Go applications in user-mode analysis types like basic hotspots, locksandwaits and concurrency. If you need to make algorithm analyses including information about context switches and waits, please use advanced-hotspots with stacks.

BR,

Vladimir

vtune 2018 crashed when collecting locksandwaits for golang benchmark http, used --profiling-signal=33 and --no-altstack
