Don’t use multiple runs with stack collection for event-based sampling
Problem:
VTune™ Amplifier XE 2013 supports new feature called “Call Stack Collection” for hardware PMU event-based sampling. However if the user set option “Allow multiple runs” in vtune’s project properties and enable “Call Stack Collection” option, to run some predefined analysis such as snb-general-exploration, snb-memory-access, etc. It will cause segmentation fail. Example command line:
